Chrysler Building, ca. 1979.

The eagle “gargoyles” that protrude from the 61st floor are made from a corrosion-resistant Nirosta, an alloy of chrome-nickel steel. The style of the 61st floor eagles was inspired by the hood ornaments of a 1929 Chrysler. The 31st floor is also adorned with stylized corner eagles. They are replicas of the 1929 Chrysler radiator caps.
