This Art Craft cacheted First Day Cover features the 15¢ U.S. airmail stamp issued May 3, 1963, in Silver Spring, Maryland, to mark the 100th anniversary of the first International Postal Conference held in Paris in 1863. The stamp portrays Montgomery Blair, Lincoln’s Postmaster General, with a globe and envelope motif highlighting international mail exchange.
Blair played a pivotal role in shaping modern postal diplomacy; his advocacy led directly to the 1863 Paris conference and, a decade later, to the establishment of the Universal Postal Union. The cover’s cachet reproduces a formal portrait of Blair flanked by the dates 1813–1883 and explicitly notes his contribution as “originator of what is now the Universal Postal Union.”
A notable detail is the stamp’s airmail designation despite commemorating an event that predates aviation, underscoring the U.S. Post Office’s long-standing use of airmail issues for international themes. The crisp Silver Spring postmark ties the cover to Blair’s Maryland roots.
A clean, well-centered example with strong Art Craft engraving, this FDC makes an excellent addition for collectors of U.S. postal history, Lincoln-era figures, or worldwide postal-union topicals.
