This 1971 First Day Cover features the 11¢ Air Mail booklet pane stamp, postmarked on the first day of issue in Spokane, Washington on May 7, 1971. The cover includes a block of 2¢ Frank Lloyd Wright stamps alongside the new airmail issue, creating an attractive combination FDC.
The cachet honors the pioneering era of U.S. airmail service, highlighting Jack Knight, known as "The Ace of the Air Mail Service," and the historic first coast-to-coast airway established in 1921. The artwork depicts an early biplane, a route map from San Francisco to New York, and period aviation imagery.
A notable detail is the inclusion of contemporary "Use Zip Code" and "Mail Early in the Day" labels, tying the cover to the U.S. Postal Service's modernization efforts of the early 1970s. The Art Craft cachet adds strong visual appeal for aviation and airmail topical collectors.
A fine addition to any U.S. airmail or transportation-themed collection, this well-preserved FDC displays excellent strike and fresh colors.
