Mr. Cole. Yes; in considering that question, I made an impression from the stamp, from the type setup in a stamp which is a part of this kit at the present time. Now the typing as set up reads "L. H. Oswald, 4907 Magazine St., New Orleans, La.," and, of course, that text repeats some of the letters, a good many of the letters, which are in the rubber-stamp impression "Doctor A. J. Hideel, P.O. Box 30016, New Orleans, La.," and I made a careful comparison of these letters as taken from the stamped impression with what is shown on 813, and I found that they agree perfectly as to measurements of the type faces, and they agree as to the design of letters. Therefore, I would say that the rubber-stamp type faces from this particular kit could have been used to produce that rubber-stamp impression on 813.
Mr. Eisenberg. Could you produce the two cards which you used to record the impression of the 115 rubber-stamp kit?
Mr. Cole. Yes, sir; the second card is an impression from the date stamp which is a part of this kit, and that too agrees along the same lines with respect to measurements of the letters and the designs of the letters.
Mr. Eisenberg. Mr. Chairman, may these two cards be admitted as Commission Exhibit 816?
Mr. McCloy. They may be admitted.
(The cards referred to were marked as Commission Exhibit No. 816 and received in evidence.)
Mr. Eisenberg. Are there microscopic characteristics on rubber-stamp printing sufficient to make positive identifications?
Mr. Cole. I don't regard any to be present in this particular stamp. But while the type faces could not be regarded as perfect, I don't know of any way to determine whether the imperfections belong only to this kit or whether they would be true of all Warrior rubber-stamp kits.
Mr. Eisenberg. Did you notice any imperfections?
Mr. Cole. Well, I did not actually catalog any imperfections, but in looking at the type I had the general impression that it is not a perfect impression, certainly not as perfect as you would get from metal type in a regular printing operation.
