CLARY, District Judge.
The plaintiff, an advertising agency, brought this action on 9 separate claims against the defendant, a chain saw and small tractor manufacturer, for advertising services rendered in the amount of $4,213.04. The defendant in its answer denied liability on all 9 claims and counterclaimed against the plaintiff in the amount of $3,919, alleging late delivery and poor quality of a sales presentation manual, one of the items in dispute in this action. Specifically the defendant alleged that the failure to have this sales book for the Fall 1955 selling season caused a decline of its sales and the resultant loss.
The case was tried to the Court without a jury. From the pleadings and proof the Court makes the following

This includes costs for production of advertisements as well as collateral material.
“The above does not include development of plans, promotions, schedules, costs, etc. — for which no charge is normally made by the agency.”
“2. Costs for job preparation (copy, layout, service) above are subject to revision or rejection if not acceptable, at no cost.

The conference of October 5, 1955, and the exchange of letters in January 1956, resulted in the reinstatement of the requirement of the original contract of April 29,1955, that job estimates be submitted for the defendant’s approval.

67. All of the work done by the plaintiff in connection with each of these nine counts was in accordance with commercially acceptable advertising standards.
68. Paragraph II k of the original Written agreement of April 29, 1955, is not applicable to the matters in controversy in this action. It applies only where there is a cancellation of part or all of “an authorized advertising schedule”. There is no evidence in this action of the cancellation of an advertising schedule.
Counterclaim
69. The defendant produced no evidence of the extent to which it was damaged, if any, during the 1955 selling season for chain saws by reason of its not having a sales presentation book or that such damage, if any, was in any way caused by the plaintiff.
Discussion
The defendant denies liability in this case on the following grounds:
(1) The plaintiff failed to submit estimates of job costs as required by the written contract between the parties and that the defendant never waived this requirement.
(2) Under Paragraph II k of the written contract of April 29, 1955, the plaintiff is only entitled to recover actual expenditures when an advertising schedule is cancelled after the creative work has begun. Defendant contends that the plaintiff has failed to prove its actual expenditures since the consideration claimed at the trial included, by plaintiff’s own testimony, (N.T. 185-186), overhead and profit.
(3) The plaintiff has failed to prove the reasonable value of its services in that its two witnesses on this point were not competent.
(4) The plaintiff’s services on each of the nine counts were unsatisfactory and failed to meet commercially acceptable advertising standards.
As to the defendant’s first contention, “it is well settled that a written [412]*412agreement may be modified by a subsequent (written or) oral agreement and that this modification may be shown by writings or by words or by conduct or by all three.” Elliott-Lewis Corp. v. York-Shipley, Inc., 1953, 372 Pa. 346, 350, 94 A.2d 47, 49; see also Dora v. Dora, 1958, 392 Pa. 433, 141 A.2d 587.
The facts as testified to by both the plaintiff and defendant clearly show that the written agreement was modified by the subsequent conduct of the parties and that the defendant waived the estimate requirement from about May 10, 1955 until October 5, 1955. The Court finds that the conference of October 5, 1955 and the exchange of letters in January, 1956, resulted in a reinstatement of the original requirement that estimates be submitted. The only services performed subsequent to October 5, 1955 (exclusive of the publicity for the Toy Fair as to which there is a separate contract) which are in dispute are those rendered on Count Nine, i. e., the creation of the picture frame mailing piece and the jumbo postcards. No written estimate of the costs of this job was submitted to the defendant. However, the defendant at the conference of February 17, 1956, approved and accepted the material prepared by the plaintiff in copy and layout form and authorized the completion of this project. In the face of this conduct the defendant cannot- be heard to say that there was no waiver of the estimates. True, there was no express waiver, but in this instance the actions of the defendant speak louder than his words.
Defendant’s second contention raises the question of the applicability of Paragraph II k of the original agreement of April 29, 1955. This paragraph reads as follows:
“Should you cancel part or all of an authorized advertising schedule after the creative work has been begun by us, we bill for any expenditures for layouts, copy, art, engravings, typography, noncancellable time or space (short-rates, and any other items), plus a mutually agreeable charge for preparation and service.”
The words “plus a mutually agreeable charge for preparation and service” were crossed out and initialed by the parties on April 29, 1955. The defendant contends that by virtue of this agreement the plaintiff is only entitled to recovei actual expenditures and since the amounts claimed include overhead and profit, the plaintiff has failed to prove its actual expenditures and, therefore, there can be no recovery in this action.
Paragraph II k of the agreement of April 29, 1955 speaks of cancelling part or all of “an authorized advertising schedule * * Mr. Robert Arndt testified that this paragraph refers to the cancellation of a complete advertising schedule and not to specific jobs. The Court finds that there was no advertising schedule involved and that each of these counts refers to a specific job and that Paragraph II k is not involved in this case.
Defendant further alleges that the plaintiff has failed to prove the reasonable value of its services in that both Mr. Signor and Mr. Morgan, who testified as to the reasonableness of the amounts claimed, were incompetent to testify on this point.
Defendant objects to Mr. Signor’s testimony as to the reasonableness of the charges chiefly on the ground that Mr. Signor admitted that he had never, up to May 10, 1955, the day on which he began work for the plaintiff, billed anyone for art work or copy work. (N. T. 66). However, Mr. Signor also testified that he has been in the advertising business since 1946 and that during most of his advertising career he has been buying advertising from agencies such as the plaintiff and that frequently it was his job to judge whether or not the charges were fair for the work accomplished. (N.T. 16, 17 and 66.) On this basis the Court concludes that Mr. Signor was' competent to testify to the reasonableness of the charges made by the plaintiff.
Defendant objects to the competency of Mr. Morgan on the basis of his [413]*413admitted lack of knowledge of the chain saw industry; his lack of knowledge of the scheme of distribution of this defendant and of the fact that he was never an account executive for a chain saw manufacturer (N.T. 393-394).
Mr. Morgan testified that he has been in the advertising business for 36 years, 28 of which were spent with advertising agencies. He also testified that he has done both copy and layout work for advertising agencies and that for the past six or seven years he has been responsible for all the creative activities of the Richard A. Foley Advertising Agency of Philadelphia of which he is a part owner (N. T. 387-388). He further testified that the problems he has handled were similar to the ones he heard Mr. Signor and Mr. Strunk describe from the witness stand (N.T. 395). The attorney for the defendant did not object to the testimony of Mr. Morgan and in fact stipulated that Mr. Morgan would testify that in his opinion the charges made were fair and reasonable (N.T. 392).
On the basis of the above recited facts the Court concludes that Mr. Morgan was competent to testify as to the reasonableness of the charges made by the plaintiff.
Finally, the defendant failed to produce any evidence, other than from Mr. Strunk, that the work done by the plaintiff failed to meet commercially accepted advertising standards. The Court finds that the work done by the plaintiff did meet commercially accepted advertising standards.
This aspect of the case requires little discussion. The defendant produced no evidence of any damage to it by reason of its failure to have a sales presentation book for the 1955 selling season or that the plaintiff in any way caused the defendant to be damaged. The only evidence presented by the defendant on this question was Mr. Strunk’s statement that he felt that his sales suffered during the 1955 season because of the lack of this sales presentation book. Obviously, this is not sufficient to support the defendant’s counterclaim.

From on or about May 10, 1955 to October 5,1955, the provision of the original contract of April 29, 1955, requiring plaintiff to submit job cost estimates for defendant’s approval was modified by the conduct of the parties so that the submission and approval of such an estimate was not a condition precedent to defendant’s obligation to pay for plaintiff’s services.

[414]*41411. Defendant’s approval and acceptance of the material prepared by the plaintiff on Count Nine resulted in a second waiver of the requirement that cost estimates be submitted for defendant’s approval so that the submission and approval of such an estimate was not a condition precedent to defendant’s obligation to pay for these services.
