The first postage stamp to honor Hamilton was issued by the U.S. Post Office in 1870. The portrayals on the 1870 and 1888 issues are from the same engraved die, which was modeled after a bust of Hamilton by Italian sculptor Giuseppe Ceracchi. The Hamilton 1870 issue was the first U.S. postage stamp to honor a Secretary of the Treasury. The three-cent red commemorative issue, which was released on the 200th anniversary of Hamilton's birth in 1957, includes a rendition of the Federal Hall building, located in New York City.
