Mr. EISENBERG. Do you have any other knowledge that these are the prints of Lee Harvey Oswald? Mr. MANDELLA. No; none whatsoever. Mr. EISENBERG. And the remaining prints are photographs of what you would call latent prints? Mr. MANDELLA. Yes; they are. Mr. EISENBERG. Did you make markings on the backs of these prints, Mr. Mandella? Mr. MANDELLA. Yes; on quite a few of them I did. However, not all of them. Mr. EISENBERG. And you made those markings on the basis of--in your own hand printing? Mr. MANDELLA. My own hand printing, for certain observations I wanted recorded. Mr. DULLES. What is the nature of the marking? Mr. EISENBERG. Let's take a sample. I will pull one out at random from Commission Exhibit 660. The topmost card says "Box B," which corresponds to the label or the envelope 660--and that is No. 17. Mr. DULLES. Will you show those to the witness and see if he identifies his own writing? Mr. MANDELLA. Yes; I have made these notations. Yes; I do recognize these. Mr. EISENBERG. The next one says "Box B" and "Negative--same as box 'D' No. 7." Mr. MANDELLA. Yes. Mr. EISENBERG. You have seen these as you flipped through to identify that these are the same photographs? Mr. MANDELLA. Yes. Mr. EISENBERG. Let the record show that these photographs are photographs of latent prints taken by or under the supervision of Mr. Sebastian Latona, and he has just testified that these photographs were taken of objects which were identified earlier in Commission proceedings. Mr. Latona transmitted these photographs to me directly, and I in turn transmitted them to Mr. Mandella and Mr. Mooney, who is also present in this hearing room. Mr. Mandella, do you know what total number of identifiable latent prints were contained in these exhibits that you just identified--exclusive of 657, which contained the inked or known finger and palm prints? Mr. MANDELLA. No; but I have this outline here. Mr. EISENBERG. Just approximately would you say how many identifiable prints there were? Mr. MANDELLA. Thirty. Mr. EISENBERG. Some 30 odd prints? Mr. MANDELLA. Some 30. Mr. EISENBERG. And did you identify certain of those prints as being the finger or palm prints of Lee Harvey Oswald? Mr. MANDELLA. Yes; I did. Mr. EISENBERG. Could you tell us which of those prints you so identified? Mr. MANDELLA. There was a photograph, a photograph of the underside of the gun barrel, Commission Exhibit No.---- Mr. EISENBERG. That is Commission Exhibit No. 658, and I will hand you that photograph now. You are referring to this photograph? Mr. MANDELLA. Yes. Mr. EISENBERG. And can you read the writing on the back of that? Mr. MANDELLA. "Right palm Oswald underside gun barrel." Mr. EISENBERG. Is that in your handwriting? Mr. MANDELLA. Yes; it is in my handwriting. Mr. EISENBERG. Did you determine what portion of the right palm that was, Mr. Mandella? Mr. MANDELLA. Yes; it is the right side of the right palm, this area right here.
