American Credo Series
On January 20, 1960, the US Post Office Department issued the first stamp in the American Credo Series.
The Post Office Department created the American Credo Series to “re-emphasize the ideals upon which America was founded and to honor those great Americans who wrote or uttered the credos.” The stamps were designed to resemble colonial currency. Also, symbols that relate to the statement are used in the designs, as well as a likeness of the author’s signature. One hundred distinguished Americans chose the individual principles.
