"I like this idea," George Maciunas wrote to Ben Vautier in 1966, "very nice & easy to produce." Oldenbourg was a friend of Vautier's and the two had participated together in various Fluxus activities in Nice, France, in the mid-sixties.
The work consists of hardened plaster in a jar. It was the only work produced by Oldenbourg for Fluxus, before he and Maciunas had a falling out following his arrest in Prague.
