4.5c White House from 1938
These dark gray beauties from 1938 come from a series called The Presidential Issue, nicknames “the Prexies” by collectors. In that year, the post office issued a definitive stamp of the 29 presidents in office between 1789 and 1938. Each was given a different color and denomination, and half cents were given to the three stamps that did not depict a president: Benjamin Franklin, Martha Washington and this stamp of the White House.
