Mr. Cadigan. Yes.
Mr. Eisenberg. So at least if the procedure had been followed, any negative you had would be a negative of a document before it had been treated for fingerprints, is that correct?
Mr. Cadigan. That is correct.
Mr. Eisenberg. Now, returning to Commission Exhibits Nos. 820 and 819, did you prepare a photograph which would show the remnants of the signature A. J. Hidell on the Commission Exhibit No. 820?
Mr. Cadigan. No.
Mr. Eisenberg. Is the preparation of such a photograph possible?
Mr. Cadigan. I doubt it very much, because the indentations are so faint that the enlargement would serve no useful purpose. Actually, the best examination is by low-power magnification under the proper lighting.
Mr. Eisenberg. Did you attempt to determine whether the signature of Lee H. Oswald on this card was written by Lee H. Oswald?
Mr. Eisenberg. What was your conclusion?
