In spite of the information shown by the Library of Congress, the image appears to have been one used for Mink's 1972 presidential run. Lori Ferber Presidential Collectibles has the full poster, noting that it was produced by the Patsy Mink for President Committee. Further confirmation is found in the Longview Daily News 13 March 1972, p. 12 which carries a copy of the poster.
