Oswald also used incorrect names other than Hidell, but these too appear unconnected with any form of conspiracy. Oswald’s last name appears as “Lee” in three places in connection with his trip to Mexico City, discussed above. His tourist card was typed by the Mexican consulate in New Orleans, “Lee, Harvey Oswald.”[C6-618] However, the comma seems to have been a clerical error, since Oswald signed both the application and the card itself, “Lee H. Oswald.” Moreover, Oswald seems originally to have also printed his name, evenly spaced, as “Lee H Oswald,” but, noting that the form instructed him to “Print full name. No initials,” printed the remainder of his middle name after the “H.” The clerk who typed the card thus saw a space after “Lee,” followed by “Harvey Oswald” crowded together, and probably assumed that “Lee” was the applicant’s last name. (See Commission Exhibit 2481, p. 300.) The clerk who prepared Oswald’s bus reservation for his return trip wrote “H. O. Lee.” He stated that he did not remember the occasion, although he was sure from the handwriting and from other facts that he had dealt with Oswald. He surmised that he probably made out the reservation directly from the tourist card, since Oswald spoke no Spanish, and, seeing the comma, wrote the name “H. O. Lee.”[C6-619] Oswald himself signed the register at the hotel in Mexico City as “Lee, Harvey Oswald,”[C6-620] but since the error is identical to that on the tourist card and since he revealed the remainder of his name, “Harvey Oswald,” it is possible that Oswald inserted the comma to conform to the tourist card, or that the earlier mistake suggested a new pseudonym to Oswald which he decided to continue. In any event, Oswald used his correct name in making reservations for the trip to Mexico City, in introducing himself to passengers on the bus, and in his dealings with the Cuban and Soviet Embassies.[C6-621] When registering at the Beckley Avenue house in mid-October, Oswald perpetuated the pseudonym by giving his name as “O. H. Lee,”[C6-622] though he had given his correct name to the owner of the previous roominghouse where he had rented a room after his return from Mexico City.[C6-623] Investigations of the Commission have been conducted with regard to persons using the name “Lee,” and no evidence has been found that Oswald used this alias for the purpose of making any type of secret contacts. Oswald is also known to have used the surname “Osborne” in ordering Fair Play for Cuba Committee handbills in May 1963.[C6-624] He also used the false name D. F. Drittal as a certifying witness on the mail-order coupon with which he purchased his Smith & Wesson revolver.[C6-625] He used the name Lt. J. Evans as a reference on an employment application in New Orleans.[C6-626]
