Based in Russia in the early 20th century, Constructivism was a radical, influential art movement dedicated to inventing new forms of art that reflected the modern, industrial world. Many of the Constructivists—Vladimir Tatlin, El Lissitzky, and Alexander Rodchenko, among them—considered themselves “artist-engineers,” creating geometric works that combined modern technology with modest materials. On the auction market, record sales for Constructivism include Rodchenko’s Construction No.95 (1919) for $4.5 million, Liubov Popova’s Still Life with Tray for $3.5 million, and Naum Gabo’s Linear Construction in Space No. 3, with Red (1957) for $2.4 million.
