There is a theory that in the large lake Vostok, which lies uder the ice of Antarctica at a depth of 4000 meters, some primitive life forms - microbes and bacteria - could exist. They may have been living for a million years. To prove this theory a special drilling rig has bored a 3623m well. Prills of the bottom and ice are being studied. In common with the French and American scientists the Russians carry out radiological and seismic explorations of the lake. The souvenir sheet also features the national flags of the countries taking part in the exploration, a cat train tractor and a plane AH-3T.
