Artist's book. Published to accompany an exhibition held at the Acme Gallery, London, 3 - 15 July 1978 "I wedged a red stack of timber between flour and ceiling in the ACME Gallery in London ... Each day the artist made a record of development and these photographs were placed alongside the sculpture. A grid of 100 photographs in all described the complete process of work. This booklet is made using photographs taken from that documentation."--Artist's preface.
