Gin flavored stamps

Harry Stewart New (1858 – 1937) was a U.S. Senator from Indiana from 1917 until 1923. He then served as the Postmaster General from 1923 to 1929 under Presidents Harding, Coolidge and Hoover.

During his term as postmaster general, New proposed two influential ideas - the honoring of distinguished Americans with stamps, and flavored glue on the back of stamps.

Postmaster New, a secret "wet" in Hoover's Prohibition "dry" administration, even commissioned a gin-flavored stamp that never made it to production according to Wikipedia.

The Office of the Postmaster General was created in 1789. For a complete list of all the Postmasters General of the United States, click here.
