Oswald’s personally-owned vintage glossy 10.25 x 8 photo of the 1956 US Marine Corps Platoon 2060 in San Diego, annotated on the reverse by Oswald in pencil to identify some of his classmates, including himself, “Oswald.” Oswald is seen fourth from the left on the second level. In very good condition, scattered surface creases, a tiny tear to left edge, and small circular label affixed to reverse upper left. Accompanied by a letter of authenticity from his older brother, Robert L. Oswald. As Oswald had only been accepted into the Marines on October 24, 1956, this photo is from very early in his three-year stint in the military. He was first trained in the use of the M1 rifle in San Diego during this period and became a reasonably competent rifleman, initially earning the designation of ‘sharpshooter’ before being downgraded to ‘marksman.’ RR Auction COA.
