The Bulldozer Exhibition was an unofficial art exhibition on a vacant lot in the Belyayevo urban forest by Moscow and Leningrad avant-garde artists on 15 September 1974. The exhibition was forcefully broken-up by a large police force that included bulldozers and water cannons, hence the name.

Lidiya Masterkova, also Lydia Masterkova, was a Soviet-born French painter, and part of the non-conformist Lianozovo Group along with Oscar Rabin. She was strongly influenced by Abstract Expressionism, which she was exposed to at the exhibition of foreign artists held during the World Festival of Youth and Students in Moscow (1957).
