The mask element in this work is made from the top of a plywood leg splint designed by Charles and Ray Eames and manufactured in 1942-3. The metal L-bar is part of the Eames-designed storage units (ESU 400s) which were manufactured in 1950-5. Boyce compares the ethos in which the objects were originally made during the post-war boom (using manufacturing techniques developed by the military for mass-production), to the cultural role they now fulfil, based on fashionable taste and monetary value. He deliberately altered the items - making the leg splint into a tribal mask and the L-bar into a spear - in order to highlight their changed role.
