The 15-cent American Architecture commemorative stamps were first placed on sale at Kansas City, Missouri, on June 4, 1979. The block of four stamps shows examples of early American architecture. Represented are the Virginia Rotunda, the Baltimore Cathedral, the Boston State House, and the Philadelphia Exchange. Each example represents architecture of enduring beauty, strength and usefulness.
The stamps were designed by Walter D. Richards and were issued in sheets of forty-eight.
