The Nationalities of the Soviet Union Salute the Heroic Cosmonauts

Part of the enormous mural on the roof of the State History Museum (formerly Lenin Museum), Bishkek (formerly Frunze), Kyrgyzstan (formerly Kyrgyz SSR)
There was also a really very striking mural of Mother Russia (wielding a sword with the gold star on the pommel) defeating a Nazi warrior in an iron-horned helmet riding a huge bull with a garland of skulls and wielding a sword with the swastika on the pommel, but it took up so much of the ceiling that I couldn't get a photo that wasn't horribly foreshortened.
