It does indeed have an arse, pulsating veins and a set of balls to go with it! - The city of Denver commissioned the fiberglass sculpture from New Mexico artist Luis Jimenez in 1993, two years before the airport opened. In 2006, Jimenez was killed when a section of the unfinished horse fell from a hoist at his Hondo, New Mexico, studio. Jimenez's sons, Adan and Orion, completed the sculpture, which was installed Feb. 11, 2008.
