UNITED STATES POST OFFICE on 6 September 1952 issued a 3-cent postage stamp commemorating the Centennial of the American Society of Civil Engineers (1852–1952).
The stamp featured in the lower left an 1852-era covered bridge and to the right it depicted the George Washington Bridge in front of the New York City skyline, as well as the society's emblem.
This blue coloured stamp was printed by the U.S. Bureau of Engraving and Printing, using a Rotary Press. The first day of issue was in Chicago, Illinois.
