'Linear Construction No.2' exists in over twenty versions, both standing and hanging. The light-catching nylon filament is wound around two intersecting plastic planes. The stringing gives a delicate sense of three dimensions in the complicated patterns created by the irregular lobe shapes of the transparent plastic. It was developed from Gabo's unrealised project for the lobby of the Esso Building in New York in the late 1940s. Two sculptures similar to 'Linear Construction No.2' were designed to be located on top of the two revolving lobby doors, turning slowly. It was one of Gabo's favourite works and was presented to the Tate in memory of the art historian Herbert Read.
