Congress finally provided for the issuance of stamps by passing an act on March 3, 1847, and the Postmaster-General immediately let a contract to the New York City engraving firm of Rawdon, Wright, Hatch, and Edson. The first stamp issue of the U.S. was offered for sale on July 1, 1847, in New York City, with Boston receiving stamps the following day and other cities thereafter. They consisted of an engraved 5-cent red brown stamp depicting Benjamin Franklin (the first postmaster of the U.S.), and a 10-cent value in black with George Washington. Like all U.S. stamps until 1857, they were imperforate.
