Issued by the Soviet Union in 1960, this stamp commemorates the International Federation of Automatic Control (IFAC) Congress held in Moscow. The design features a bold “IFAC” emblem overlaid on a target-like control motif, symbolizing precision and scientific advancement in automation. A stylized depiction of Moscow’s skyline, likely including a Stalinist skyscraper, reinforces the host city’s prominence in global scientific collaboration. This issue reflects the USSR’s strong emphasis on technological progress during the Cold War era. A notable thematic piece for collectors interested in science, engineering, and international conferences.
