This 1966 5¢ Migratory Bird Treaty First Day Cover features an Artmaster cachet depicting Canada geese and mallards in flight over a marsh, issued March 16, 1966, in Pittsburgh, Pennsylvania. The stamp commemorates the 50th anniversary of the 1916 treaty between the United States and Canada.
The Migratory Bird Treaty established international protection for shared bird populations, leading to the Migratory Bird Treaty Act of 1918. It remains a cornerstone of North American conservation, regulating hunting seasons and habitat protection across borders.
The Artmaster design highlights the anniversary with a distinctive oval emblem and detailed wildlife illustration, signed by the cachet maker. The cover is addressed to Nancy Lou Ludmer in Wood-Ridge, New Jersey, a small Bergen County borough.
A fine example for collectors of wildlife topicals, U.S. commemoratives, or Artmaster cachets, with clear postmark and attractive artwork.
