Color printed postcard captioned "General Post Office Building, 8th Avenue & 31st Street, New York City," card 12, showing the long colonnaded post office with its broad front steps, an American flag and a few pedestrians. Published by Alfred Mainzer, 118 East 28th St., New York 16, N.Y.; number 14806 on the front. Standard size, about 3.5 x 5.5 inches, divided back reading "Place One Cent Stamp Here." Unposted and unwritten, in clean used condition with light corner wear.

The inscription band over the entrance is printed small but legible in part. A good card for post office, postal history and New York City architecture collectors.
