This Art Craft cacheted First Day Cover features the 11¢ airmail booklet pane stamp issued May 7, 1971, and postmarked in Spokane, Washington on the official first day of issue.
The stamp and cachet commemorate Jack Knight, legendary airmail pilot known as “the ace of the air mail service,” and the historic first coast-to-coast airway established in 1921. The artwork depicts Knight’s portrait, a 1920s biplane, and the transcontinental route connecting San Francisco, Chicago, and New York.
A notable detail is the vertical pair of 11¢ stamps shown on the right with the “FIRST DAY OF ISSUE” inscription and the contemporary “Use Zip Code” slogan labels, making this a colorful and informative airmail FDC.
A fine addition to any airmail, aviation, or U.S. postal history collection, this cover displays fresh colors and a clear Spokane postmark.
