matched the handwriting specimens Pip-kins had given Inspector Crowley. On cross-examination by defense counsel, the following testimony was elicited:
Q. Mr. Somerford, when Mr. Pipkins was at your office did you take other samples of writing and letters from him?
Q. Was that before or after you examined the government samples in relation to the check?
A. That was after I made the preliminary examination of Government Exhibit 1 writing [the forged check] with that in Government Exhibit 5 [the handwriting exemplars].
Q. Were the subsequent samples that you took necessary, and did they form a vital part of your opinion that the signature of Milton Chambers was written by the same person as contained on the government’s samples?
A. I must say that they didn’t contribute markedly to the examination, beyond the samples contained in Government Exhibit 5.
Q. So you would be able to testify, then, based merely on the exhibits, without any reference, or being able to wipe from your mind the subsequent samples that yoú took?
A. Well, I would say that, yes. .
After this testimony, the court overruled the appellant’s objection with the reservation that the government not comment upon the fact of Somerford’s previous employment by defense counsel. The jury was summoned, and Somerford repeated his incriminating testimony.1

Pipkins contends that the trial court’s refusal to apply the attorney-client privilege to the testimony of Somerford was reversible error. He argues that the handwriting specimens which Pipkins gave Somerford, as well as Somerford’s report of his findings, were privileged communications.
The attorney-client privilege prohibits the disclosure of the substance of communications made in confidence by a client to his attorney for the purpose of obtaining legal advice. United States v. Hodgson, 492 F.2d 1175, 1177 (10th Cir. 1974); Clanton v. United States, 488 F.2d 1069, 1071 (5th Cir. 1974), cert. denied, 419 U.S. 877, 95 S.Ct. 140, 42 L.Ed.2d 116 (1974); United States v. Kendrick, 331 F.2d 110, 113 (4th Cir. 1964); J. P. Foley & Co. v. Vanderbilt, 65 F.R.D. 523, 526 (S.D.N.Y.1974). In appropriate circumstances the privilege may bar disclosures made by a client to non-lawyers who, like Somerford, had been employed as agents of an attorney. United States v. Kovel, 296 F.2d 918, 921 (2d Cir. 1961); Burlington Industries v. Exxon Corp., 65 F.R.D. 26, 40 (D.Md.1974); United States v. Schmidt, 360 F.Supp. 339, 346 (M.D.Pa.1973); 8 Wigmore, Evidence (McNaughton rev. 1961) § 2301.
The attorney-client privilege, however, is not a broad rule of law which interposes a blanket ban on the

The government also offered the testimony of a fingerprint expert who testified that a latent fingerprint on the forged check matched the defendant’s left thumbprint. The defense subsequently stipulated to the fingerprint. Pipkins took the stand in his own defense. He testified that he had seen and handled the check during a card game with Ernest Middleton (alias Johnny Coffey), but that he had returned the check to Middleton after a cursory examination. Middleton, called as a witness by the court, freely admitted having forged and cashed stolen government checks on several occasions. He further testified that on several occasions he had been in the company of the appellant when the latter was in possession of stolen Treasury checks. Middleton denied, however, that he had ever had in his possession the check made payable to Chambers or that he had ever given Pipkins that check.
