Mr. Cadigan. That the Lee H. Oswald signature on Commission Exhibit No. 820 was written by Lee H. Oswald.
Mr. Eisenberg. What about the signature "A. J. Hidell"?
Mr. Cadigan. I was unable to reach a conclusion. First of all, at the time I compared this signature the known standards of Lee Harvey Oswald were inadequate for this particular comparison.
I did, however, note that there were certain differences in this signature that indicate the possibility of someone other than Oswald having prepared it. But in my opinion, the characteristics I observed were not of sufficient weight for a positive opinion in this regard.
Mr. Eisenberg. Could you note those characteristics?
Mr. Cadigan. Yes; I think the capital letter "A" and the capital letter "H" in "Hidell" are different from the "A's" that Oswald makes, that appear in the enlarged photographs, Cadigan Exhibits Nos. 4 through 10.
Mr. Eisenberg. Anything else?
Mr. Cadigan. I think the lower case "d," especially in the rounded shape of the body of it and the relatively short height of the staff, so that the staff compared to the body is very short. The "J" is made different or in a different manner than Oswald regularly makes or usually makes his "J's" in the known standards, but again it is a question of judgment as to whether you believe a combination of characteristics is enough to either eliminate or identify. In this instance, in my opinion, these differences point to the possibility of another writer other than Oswald.
Mr. Eisenberg. You indicated before, also, that there was another ink used.
Mr. Cadigan. That is correct. This, of course, in and of itself, is of no consequence, since the same person can use two different pens, so the color of the ink would not be, in my mind, significant.
