The 5-cent Urban Planning commemorative stamp was first placed on sale at Washington, DC, on October 2, 1967, during a meeting of experts concerned with all phases of city life fifty years into the future. Host to the international meeting was the American Institute of Planners.
Francis Ferguson, instructor in the School of Architecture, Division of Urban Planning, Columbia University, New York City, designed the stamp, which depicts a bird's-eye view of a planned city. The city area was white, black, and light blue, this last-named ink being applied by offset. Dark blue and black areas were printed on the Giori press.
The stamp was issued in panes of fifty, with an initial printing of 120 million.
