Great work ! ! But if we stay in history, Yves's "Zone of Inmaterial Pictorialy Senceabilty" is much beter. They were a direct challange on the marketability of art. The "zones" consisted of nothing, only a declared "space", (air) or better yet, only the "idea". Nothing that could be resold later at profit. The first pure conceptual art work. By the way, 7 "Zones" were purchased, (at 200 bucks in pure gold), including by the Blankfort family from LA.
