As promised, German artist Hans-Peter Feldmann and Guggenheim’s Hugo Boss Award winner has turned his $100,000 prize into 100,000 used dollar bills and had them pinned tightly together on the walls and columns of the museum’s second floor gallery. When asked if he wished the work was permanent, Feldmann said “No way! I want the money.”

Guards are keeping a vigilant eye on the fluttering greenery, lest some little art thief tries to yoink a money leaf. Tempting, isn’t it? (Photos: David Heald/ Solomon R. Guggenheim Foundation via Collossal)
