A rare image indeed. Leon Trotsky appearing in a Soviet picture. He was never formally rehabilitated by the Soviet government, despite the Glasnost-era rehabilitation of most other Old Bolsheviks killed during the Great Purges of Joseph Stalin.
This stamp, from 1987, depicts Trotsky, Lenin, and Dzershinski pouring over a map of Moscow in the painting, “On the Eve of the Storm,” by V. V. Pimenov.
