There are several candidates for the title of the first commemorative. A 17-cent stamp issued in 1860 by New Brunswick, showing the Prince of Wales in anticipation of his visit is one possibility. Often cited as the world’s first commemoratives are the sixteen stamps of the United States Columbian Issue, produced to celebrate the World Columbian Exposition in Chicago honoring the 400th anniversary of Christopher Columbus's arrival in the New World in 1492. (Illustrated here is the $1 stamp from the series: "Isabella pledging her jewels.")
