Matte-finish 10.5 x 13.75 photo, signed and inscribed in ink, “To Elmer W. Moore with appreciation, Lyndon B. Johnson.” Moore (1909–2001), a Secret Service agent for nearly four decades, spent a year on Harry S. Truman’s presidential detail. Following the assassination of JFK, Moore would play a central role in the investigation headed by Chief Justice Earl Warren. After Warren began to receive death threats, he specifically requested that Moore, a longtime friend, be assigned as his personal security detail. Moreover, Moore played a crucial role in the investigation itself, conducting interviews with Jack Ruby (an acquaintance), Ruby’s roommate, several employees of the Texas School Book Depository, and the doctors at Parkland Hospital who desperately attempted to save the president’s life. The photo comes directly from Moore’s family and has never before been offered for sale. A few creases to borders (one very slightly touching background at upper left), otherwise fine condition. An association of exceptional interest! Auction LOA John Reznikoff/PSA/DNA and R&R COA.
