The A.E.F. booklet panes were issued in September 1917, primarily for use by the American Expeditionary Forces in Europe during World War I. Only 3,000 panes were prepared of both the 1c and 2c denominations. By October they were no longer needed for the post card rate, as Congress passed a vote allowing first-class mail to be sent free of charge by active members of the Armed Forces. Many of the panes were destroyed.
