Send greetings to friends and family overseas with the latest international stamp from the U.S. Postal Service featuring a colorful illustration of an 18th-century compass rose.

The 32-point compass rose from the Collections of Maine Historical Society depicted on this round stamp was drawn by Lucia Wadsworth, the aunt of poet Henry Wadsworth Longfellow, in her school geography notebook in 1794, when she was 10 years old. She brightly colored the directional points in blue, red, yellow, and green.

A compass rose is a round figure on a map that helps users of the map orient themselves by showing the direction of north and other points of the compass. The earliest known compass rose was drawn in the 1300s and was used to indicate the directions of the eight principal winds. Now they are typically shown as the four cardinal directions (north, south, east, west) and four intercardinal directions (northeast, southeast, northwest, southwest). More elaborate compass roses show the directions not only of the eight principal winds, but also the half-winds and quarter-winds, which were used as points of orientation. The term “compass rose” comes from the resemblance of the directional points to the petals of roses.
