I think this is relevant to the title of this thread because the name of the “doctor” has some similarities to the fake identification name of A.J. Hidell. Also, the post office box number only have the last two digits transposed.
From page 222 of “November 22, 1963: You Are The Jury” by David Belin:
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. 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. There is no “Dr. Hideel” licensed to practice medicine in Louisiana. There is no post office box 30016 in the New Orleans Post Office but Oswald [when he move to New Orleans] had rented post office box 30061 in New Orleans on June 3, 1963, listing Marina Oswald and A.J. Hidell as additional persons entitled to receive mail in the box. The New Orleans po9stal 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.
