On June 13, 2007, in Washington, DC, the Postal Service issued a 58-cent (2-ounce rate) Margaret Chase Smith definitive stamp in one design in a pressure-sensitive adhesive (PSA) pane of twenty. Richard Sheaff of Scottsdale, Arizona, designed the stamp.
This eighth issuance in the Distinguished Americans series honors Margaret Chase Smith, the first Republican woman elected to the US Senate and the first woman to serve in both houses of Congress. Artist Mark Summers of Waterdown, Canada, created the portrait on the stamps. The artwork is based on a photograph by the Harris and Ewing studio, dated 1948.
Ashton-Potter (USA), Ltd., printed 100 million stamps in the offset/intaglio process.
