Fantastic hand-addressed and free-franked address panel as president, 5 x 3.25, addressed by Jefferson to "Mr. Matthew Cary, Bookseller, Philadelphia, and franked in the upper left, "free, Th: Jefferson, Pr. U.S." Postmarked at Washington on March 7, [no year]. Archivally encapsulated in Mylar, mounted, matted, and framed with a gilt-edged porcelain ‘Oval Office Collection’ portrait by Christian Bell Porcelain and nameplate to an overall size of 11.75 x 14.75. In very good to fine condition, with staining to the right side of the central vertical fold, and scratching to the top of the frame.Mathew Carey was an Irish-born American publisher and economist who lived and worked in Philadelphia, and is best remembered for his important magazine The American Museum, which counted the likes of George Washington, Benjamin Franklin, James Madison, and Thomas Jefferson among its subscribers. Carey was an ardent supporter of a strong American Navy, and he corresponded frequently with John Adams and other statesmen on the topic; his correspondence with Jefferson generally related to the purchase and sale of books. It is likely that this cover contained President Jefferson's letter of March 7, 1805, which contained a draft on the Philadelphia Bank for $10.37 to pay for a Bible. A spectacular free frank boasting an excellent association.Format: Free Frank
