This six-cent stamp, issued in 1968, commemorates the 300th anniversary of Father Jacques Marquette's founding of the mission at Sault Ste. Marie. This mission became the first permanent European settlement in what is now Michigan. The stamp depicts Marquette and Louis Jolliet in a canoe, symbolizing their famous 1673 expedition down the Mississippi River. Marquette's work as both a missionary and an explorer was instrumental in establishing French influence in the Great Lakes region and fostering early relations with Native American tribes. This stamp recognizes his dual role as a man of faith and a pioneering explorer.
