A classic U.S. Internal Revenue documentary stamp issued during the wartime Series of 1943, printed in bright carmine-red and featuring a bold numeral “1” enclosed within a detailed geometric security rosette. This 1¢ denomination was used on legal and financial documents to pay federal documentary tax during WWII. Its crisp engraving, ornate frame, and clean typography showcase the Bureau of Engraving and Printing’s high-security design style. A desirable addition for collectors of revenues, wartime tax issues, or U.S. fiscal history.
