This colorful vintage postcard was never used.  It's another one of my fun eBay finds. The reverse side reads,

Chrysler Building

77 stories - 1,046 feet high - second highest building in the world. The spire, made of Nirosta metal that will not rust, is a 185-foot multi-arched dome shaped to a needle-point finial.

The card was published by the Interborough News Company of New York, and is a "Genuine Curteich-Chicago "C. T. Art-Colortone Postcard."
