Fog Sculpture #08025 (F.O.G.), 1998 was commissioned by Robert Rauschenberg to coincide with the opening of his 1998 retrospective at the Guggenheim Museum Bilbao ("F.O.G." stands for "Frank O. Gehry"). Soon after the opening, Rauschenberg purchased it and donated it to the museum. Fog Sculpture #08025 (F.O.G.) is now permanently installed in the pool next to the riverfront facade of Gehry's billowing titanium structure.
