The 5-cent stamp commemorating the 175th anniversary of the Bill of Rights was first placed on sale in Miami Beach, Florida, on July 1, 1966, to coincide with the National Education Association convention.
Pulitzer prize winner Herbert L. Block designed the stamp. He is better known as "Herblock," the name he used in signing editorial cartoons for the Washington Post and for syndication in more than 200 newspapers.
The dominant feature of the shield-shaped design shows two hands in conflict. On the right is a gauntleted fist, suggestive of "the knock on the door at night," associated with tyranny, and on the left appears a bare upraised hand symbolizing the guarantees of freedom in the Bill of Rights.
The stamp was printed on the Giori press and issued in panes of fifty. An initial printing of 115 million stamps was authorized.
