U.S. #552 shows Ben Franklin, Founding Father and first postmaster of the United States. This stamp kept alive the tradition in which every new set of definitive stamps featured Franklin on the first stamp.

 

The Series of 1922-25 and the Wheels of Progress

In 1847, when the printing presses first began to move, they didn’t roll – they “stamped” in a process known as flat plate printing. The Regular Series of 1922 was the last to be printed by flat plate press, after which stamps were produced by rotary press printing.

 

By 1926, all denominations up to 10¢ – except the new ½¢ – were printed by rotary press. For a while, $1 to $5 issues were done on flat plate press due to smaller demand.

 

In 1922, the Post Office Department announced its decision to issue a new series of stamps to replace the Washington-Franklin series, which had been in use since 1908. Many criticized the change, believing it was being made to satisfy collectors rather than to fill an actual need. However, the similar designs and colors of the current stamps caused confusion, resulting in a substantial loss in revenue each year. In busy situations, postal clerks could not tell at a glance if the correct postage was being used.

 

Postal employees requested a variety of designs which could easily be distinguished from one another. Great care was taken to make sure the new designs could not be confused. Although the frames are similar, the vignettes (central designs) are distinctive. Prominent Americans, as well as scenes of national interest, were chosen as subjects for the new series.
