after. No one called for mail out of this box; indeed the only mail in the box was a Russian magazine addressed to Oswald. The single outstanding key was recovered from Oswald immediately after he was taken in custody.603

In appraising the import of Oswald's rental of post office boxes, it is significant that he was not secretive about their use. All three boxes were rented by Oswald using his true name.604 His application for box No. 2915 showed his home address as that of Alexandra De Mohrenschildt (Taylor), whose husband had agreed to allow Oswald to use his address.605 His application for the New Orleans box listed his address as 657 French Street; his aunt, Lillian Murret, lived at 757 French Street.606 On the application for box No. 6225, Oswald gave an incorrect street number, though he did show Beckley Avenue, where he was then living.607 He furnished the box numbers to his brother, to an employer, to Texas and New Orleans unemployment commissions, and to others.608 Based on all the facts disclosed by its investigation, the Commission has attached no conspiratorial significance to Oswald's rental of post office boxes.

Oswald's use of aliases is also well established. In chapter IV, the evidence relating to his repeated use of the name "A. J. Hidell," and close variants thereof, is set forth.609 Because Oswald's use of this pseudonym became known quickly after the assassination, investigations were conducted with regard to persons using the name Hidell or names similar to it. Subversive files, public carrier records, telegraph company records, banking and other commercial records, and other matters investigated and persons interviewed have been examined with regard to Oswald's true name and his known alias.610 No evidence has been produced that Oswald ever used the name Hidell as a means of making undercover contact with any person. Indeed, though Oswald did prepare a counterfeit selective service card and other identification using this name, he commonly used "Hidell" to represent persons other than himself, such as the president of his nonexistent Fair Play for Cuba Committee chapter, the doctor whose name appeared on his counterfeit international certificate of vaccination, and as references on his job applications.611

Alwyn Cole, questioned document expert for the Treasury Department, testified that the false identification found on Oswald upon his arrest could have been produced by employing elementary techniques used in a photographic printing plant.612 (See app. X, pp. 571-578.) Though to perform the necessary procedures would have been difficult without the use of expensive photographic equipment, such equipment and the needed film and photographic paper were available to Oswald when he was employed from October 1962 through early April 1963 at Jaggars-Chiles-Stovall, a commercial advertising photography firm in Dallas.613 While so employed, Oswald is known to have become familiar with the mechanics of photographic enlargements, contraction, and image distortion that would have been necessary to produce his false identification, and to have used the facilities of his employer for some personal work.614 Cole testified that the cards
