The Department issued this 3-cent stamp on February 23, 1957, through the New York, New York, post office, in honor of the Architects of America. It was first placed on sale on the centennial anniversary of the founding of the American Institute of Architects.
The subject, which dominates the left portion of the stamp, is composed of a structural mushroom-type head and shaft superimposed on a Corinthian style capital, symbolizing the progress made in architecture during that century. The word "Centennial" is arranged across the top of the stamp and "American Institute of Architects 1957," arranged in 5 lines, appears to the right of the columns. The denomination "3c" is placed in the lower left corner and "United States Postage" across the bottom. The style of lettering further reflects the simplicity of line that the artist endeavored to portray.
Designed by Robert J. Schultz, the stamp was printed by the rotary process, electric-eye perforated, and issued in panes of fifty stamps each. The printing of 120 million stamps was authorized.
