Issued in 1976 by the Soviet Union, this commemorative 6 kopeck stamp marks the 20th anniversary of the Joint Institute for Nuclear Research (JINR) in Dubna. The design features a stylized atomic symbol overlaid on a dynamic red-and-blue spiral, symbolizing the unity of scientific collaboration and nuclear energy. Below, a depiction of the JINR’s domed main building represents the institute’s architectural identity. The use of silver and vivid color contrast reflects the optimism of Soviet scientific advancement during the Cold War era.
