Exceptional vintage glossy 3.75 x 2.25 Russian postcard photo of a street in Minsk originally sent to his brother, described and signed on the reverse in blue ink, “Robert, We walk here sometimes. Lee.” Label affixed to the reverse reads, “Commission Exhibit No. 304B.” In fine condition. Originally used as evidence during the Warren Commission hearings, Oswald enclosed this postcard photo and two others in a letter to his brother sent on August 21, 1961 [letter was Commission Exhibit 303]. At the time he sent this, Oswald was desperately trying to leave the USSR and return to the United States, but encountered difficulties from both countries in arranging the paperwork for his wife and newborn daughter.
