The
1902 series of US regular stamps consisted of fourteen denominations (1c to $5) and a
special delivery stamp. The 1c Franklin is commonly found on picture postcards from 1903-1909.
The 2c-10c stamps are fairly easy to find on interesting covers, which despite being 100 years old,
are not too expensive.

Here is a 1c Franklin on a South Dakota advertising cover. L. W. Stillwell was a Deadwood, S.D.
dealer in cool stuff: Indian bead work, ancient stone relics (arrowheads), elk teeth, minerals, and fossils.
