In 1962, New Jersey-based artists Brecht and Watts (the latter a professor at Douglass College) launched a subscription service called Yam Festival Delivery Event. Inspired by the marketing techniques of Madison Avenue as well as late-nineteenth- and early-twentieth-century novelties, the event commenced upon the arrival of a simple card that invited recipients to purchase "a work" assembled by one of the two artists. The works took three forms: event scores, objects to be utilized during an event, or both. The objects ranged widely: some were fabricated by the artists, others were found, and others still were found and later altered, such as Watts's Flux Rattle.
