Tunguska event stamp, 50th anniversary. This Soviet stamp of 1958 depicts the Russian mineralogist and Tunguska event researcher Leonid Kulik (1883-1942) at right, with the Tunguska event fireball shown at left. This event, a massive explosion that took place at 07:17 on 30 June 1908, in Siberia, Russia, is thought to have been a meteorite or comet exploding. The Cyrillic and other text on the stamp includes Kulik's initials, surname and birth and death years, his profession, the Cyrillic for USSR (CCCP), the stamp's price (40 kopeks), the name and date of the Tunguska event, and 50th anniversary commemoration text.
