Blue horse Statue in Denver International Airport

The big blue statue of a rearing mustang at Denver International Airport drew praise and hatred from the very beginning. "Mustang," the giant sculpture by Luis Jimenez, who was crushed by the horse during its construction, turns 5 on Feb. 11, which is an important milestone for public art in Denver. Petitions to remove artworks aren't accepted for the first five years, a rule meant to keep public art installations from being torn down rashly. Standing on hind legs at the gateway to the airport, the towering horse makes an aggressive first impression. [Source]
