In 1920, Gabo and his brother Antoine Pevsner published the Realistic Manifesto which signaled a move away from representation in favour of a new form of art concerned with space and time. During the 1920s Gabo made a number of small sculptural reliefs, which set curved constructions in shallow boxes and niches. Gabo’s use of hard industrial materials and plastics is balanced here by the construction’s red environment, which infuses it with a warm, sensuous hue.
