This is one of Dubuffet's three monumental sculpture commissions in the United States. It has been taken to represent a standing animal, a tree, a portal and an architectural form. The sculpture is based on Dubuffet's 1960 painting series Hourioupe. The sculpture and the series of figural and landscape designs it is a part of reflects his thoughts of earliest monumental commission, for the One Chase Manhattan Plaza.
The sculpture is one of 19 commissioned artworks funded under the State of Illinois Art-in-Architecture Program throughout the building. This was commissioned by the Illinois Capital Development Board.
The sculpture is affectionately known to many Chicagoans as "Snoopy in a blender".
