Nigel Henderson's photograms, or "Hendograms" as he called them, were created using an photographic enlarger bought for him in 1949 by his friend Eduardo Paolozzi. Paolozzi returns to London and briefly stays with the Hendersons in Bethnal Green, where he and Henderson collaborate on a series of experimental photographic works.

Henderson experimented with this "crude drawing instrument", as he put it, exposing found objects and debris to light on photo-sensitive paper. He described it as a "method of drawing of all kinds of marks and energies of line and shape and texture".
