The 6-cent Daniel Boone stamp, the third in the American Folklore Series, was issued on September 26, 1968, at Frankfort, Kentucky, where the frontiersman was buried.
Louis Macouillard designed the stamp, which was printed in two yellow inks by offset with black and red applied by the Giori press. Red mingled with yellow to produce light brown. Attached to a wall of roughly-hews boards were the tools of Boone's trade—a Pennsylvania rifle, a powder horn, and a knife. The pipe tomahawk was a historical reminder that the Shawnees had adopted Boone. His birth date was carved on the wall.
The stamp was issued in panes of fifty, with an initial printing of 120 million.
