U.S.S.R. circa 1960. Color-printed educational poster, measuring 18.75 x 14.75 inches, mounted to stiff cardboard backing, with two punched holes and cord for hanging. Numeral “2” stamped to verso, with ink notation. A few faint splashmarks.
Classroom poster of pioneering French mathematician, scientist, and philosopher Rene Descartes (1596-1650), part of the “Cabinet of Mathematics” series designed to be displayed in Soviet schools. Descartes’s important contributions to mathematics included the development of Cartesian geometry, which laid the groundwork for calculus later in the seventeenth century. Captioned with his name (in Cyrillic) and dates, this portrait of Descartes maintains direct eye contact with its presumably captive viewers. A compelling artifact of Soviet mathematical education during the Cold War.
