The size is 6 ½" x 4 ½", with a pre-printed postal stamp. Postally unused, published by the Ministry of Communications of the USSR, circulation unknown. The stamp is canceled with the First Day Cover issued by the Tallinn (Estonian SSR) Post Office, dated 9 May 1975, in celebration of the 30th anniversary of victory in the Patriotic War of 1941-1945. The artwork in the left obverse pane shows a portrait of Zoya Kosmodemyanskaya, the first woman - Hero of the Soviet Union. Serving in the Red Army in a reconnaissance group specializing in subversive activity behind enemy lines, she was tasked in November 1941 with setting fire to several villages from which the Red Army had retreated, to deprive German troops from a place to rest. Needless to say, those villages still had their Soviet population in place. With or without the help from the peasants whose houses Zoya set fire to, she was captured by the Nazis, tortured and executed.

In excellent condition, just a tiny bit of storage wear to the verso.
