Quarto. 193pp. Enclosed in a pocket at the rear board is a pair of spectacles meant to view the ten stereoscopic reproductions (numbers 102-111). These best emblematize Gabo's innovations in kinetic sculpture, which he formulated under the banners of Constructivism, Kandinsky-like abstraction, and Bergsonian vitalism. Gabo's modernism, which slipped toward the moddish, emerged as much through his aesthetics as his materials for sculpture, often of plastics. The same architectural sensibilities for space and mass he brought to his paintings, drawings, and prints, which convey movements in three or four dimensions on flat planes. Bound in full gray cloth over boards. Motes of foxing to lower edge of front cover and to flyleaves, else near fine in very good dust wrapper.
