This 5-cent Crusade Against Cancer commemorative postage stamp was first placed on sale through the Washington, DC, post office on April 1, 1965.
Designed by Stevan Dohanos, the stamp publicized the "Crusade Against Cancer" and stressed the importance of early diagnosis. Due to the arrangement of the colors, it was necessary to run the sheets through the press twice, resulting in two plate numbers on each pane.
This stamp was printed on the Giori press and issued in panes of fifty. An initial printing of 115 million stamps was authorized.
