John Dubuffet's "Monument Au Fantome" sculpture in Houston, Texas's Discovery Green Park. Its title means “Monument to the Phantom” or imaginary city, in French. There are seven individual forms that represent different features of this city, including a church, hedge, chimney, dog, phantom, tree and mast. Dubuffet was inspired by the art of outsiders, which he called “L’Art Brut”. This sculpture is painted fiberglass over steel frames, and the tallest piece is 33 feet high.
