U.S. Mail One Cent Prepaid Stamp - Historical Postal Marking #105 (License: Personal Use)

This black-ink circular postmark features bold serif lettering reading “U.S. MAIL” at the top, “ONE CENT” in the center, and “PREPAID” along the bottom arc-a standard design used during the mid-to-late 1800s to validate prepayment of postage. The slightly irregular edges and ink bleed suggest hand-stamped application on paper mail. Such marks were applied by post offices before adhesive stamps became widespread or as supplementary proof of payment.

Used on historical mail correspondence, this image serves collectors, educators, and historians researching U.S. postal evolution; commonly featured in museum exhibits, auction listings, and digital archives about 19th-century philately.
