The B. Free Franklin Post office is the only free colonial-themed post office operated by the US Postal Service in existence. It also proves itself in staying true to the period in which it was created (for instance, it does not fly the American flag as there was no flag in 1775). This post office honors Benjamin Franklin, our nation's first post master, and explores his history and the history of the postal service through an onsite museum. In the museum, find postal memorabilia as well as objects and articles of historical interest and significance. The postal-stamp letters receive from going through this office still bear the mark "B. Free Franklin".
