This complete postally used sheet of 100 stamps from the 1949 eighth definitive issue of the Soviet Union depicts a miner in profile, holding a pneumatic drill, rendered in detailed gray-black tones. The image reflects the glorification of industrial labor during Stalin's postwar reconstruction era, exemplifying socialist realism through its heroic portrayal of a male worker. Designed by Vasily Zavyalov, this issue was part of a broader propaganda campaign emphasizing economic productivity and the valorization of manual labor. Issued on April 28, 1949, the stamp was in circulation through to the end of the pre-decimal kopek period, and was widely used across the USSR. Printed via offset lithography on ordinary unwatermarked paper, the sheet features comb perforation 12 x 12¼. The margins are intact and include full perforation guides and press control markings. The reverse shows a pinkish hue due to offset ink penetration typical of the era. Several circular cancellations are visible from Moscow, dating from the 1950s, suggesting philatelic or bulk mailing usage, and confirm authentic postal handling.
