Mr. Pena. Well—you say you do know?
Mr. Liebeler. Yes.
Mr. Pena. Okay. I took two courses in investigation work, one from the International Detective School, and one from the Applied Sciences of Chicago. The big man there is an ex-FBI man, Mr. Dickerson Cook. So I took that course, too. After I finished, he sent me a letter. I like investigation very much.
Mr. Liebeler. Let me point out to you a young man in this picture. He is the second man to Oswald's right and behind. He is standing there with some leaflets in his hand. He has a white, short-sleeved shirt on and a tie, and he appears to be handing out leaflets. Did you ever see that man before?
Mr. Pena. I don't believe so.
Mr. Liebeler. Could he have been the man who was with Oswald in the bar?
Mr. Pena. I couldn't say.
Mr. Liebeler. You don't recognize anybody else in that picture except Oswald, is that correct?
Mr. Pena. Yes.
Mr. Liebeler [handing picture to witness]. I show you a picture which has been previously identified as "Pizzo Exhibit No. 453-A," and ask you if you recognize anybody in that picture.
