Flag of the Russian Soviet Federative Socialist Republic
The penultimate USSR-era flag was adopted by the Russian Soviet Federative Socialist Republic (RSFSR) in 1954 and used until 1991. The flag of the Russian SFSR was a defacement of the flag of the USSR. The constitution stipulated:The state flag of the Russian Soviet Federative Socialist Republic (SFSR) presents itself as a red, rectangular sheet with a light-blue stripe at the pole extending all the width [read height] which constitutes one eighth length of the flag.

The State Flag of the Union of Soviet Socialist Republics, or simply the Soviet flag, was a red banner with two communist symbols displayed in the canton: a gold hammer and sickle topped off by a red five-point star bordered in gold. The flag's design and symbolism are derived from several sources, but emerged during the Russian Revolution. It has also come to serve as the standard symbol representing communism as a whole, recognized as such in international circles, even after the dissolution of the Soviet Union in 1991.
