Among other identification cards in Oswald’s wallet at the time of his arrest were a Selective Service notice of classification, a Selective Service registration certificate,[C4-23] and a certificate of service in the U.S. Marine Corps,[C4-24] all three cards being in his own name. Also in his wallet at that time were a Selective Service notice of classification and a Marine certificate of service in the name of Alek James Hidell.[C4-25] On the Hidell Selective Service card there appeared a signature, “Alek J. Hidell,” and the photograph of Lee Harvey Oswald.[C4-26] Experts on questioned documents from the Treasury Department and the FBI testified that the Hidell cards were counterfeit photographic reproductions made by photographing the Oswald cards, retouching the resulting negatives, and producing prints from the retouched negatives. The Hidell signature on the notice of classification was in the handwriting of Oswald.[C4-27] (See app. X, p. 572.) In Oswald’s personal effects found in his room at 1026 North Beckley Avenue in Dallas was a purported international certificate of vaccination signed by “Dr. A. J. Hideel,” Post Office Box 30016, New Orleans.[C4-28] It certified that Lee Harvey Oswald had been vaccinated for smallpox on June 8, 1963. This, too, was a forgery. The signature of “A. J. Hideel” was in the handwriting of Lee Harvey Oswald.[C4-29] There is no “Dr. Hideel” licensed to practice medicine in Louisiana.[C4-30] There is no post office box 30016 in the New Orleans Post Office but Oswald had rented post office box 30061 in New Orleans[C4-31] on June 3, 1963, listing Marina Oswald and A. J. Hidell as additional persons entitled to receive mail in the box.[C4-32] The New Orleans postal authorities had not discarded the portion of the application listing the names of those, other than the owner of the box, entitled to receive mail through the box. Expert testimony confirmed that the writing on this application was that of Lee Harvey Oswald.[C4-33] Hidell’s name on the post office box application was part of Oswald’s use of a nonexistent Hidell to serve as president of the so-called New Orleans Chapter of the Fair Play for Cuba Committee. (As discussed below in ch. VI, p. 292.) Marina Oswald testified that she first learned of Oswald’s use of the fictitious name “Hidell” in connection with his pro-Castro activities in New Orleans.[C4-34] According to her testimony, he compelled her to write the name “Hidell” on membership cards in the space designated for the signature of the “Chapter President.”[C4-35] The name “Hidell” was stamped on some of the “Chapter’s” printed literature and on the membership application blanks.[C4-36] Marina Oswald testified, “I knew there was no such organization. And I know Hidell is merely an altered Fidel, and I laughed at such foolishness.”[C4-37] Hidell was a fictitious president of an organization of which Oswald was the only member.[C4-38]
