Louisiana joined the Union on April 30, 1812, becoming the 18th state. The Louisiana quarter design incorporates the image of a brown pelican, a trumpet with musical notes, and the outline of the Louisiana Purchase territory, with the inscription "Louisiana Purchase." Louisiana's nickname, the "Pelican State," honors the state bird — the brown pelican — which is indigenous to Louisiana. The trumpet and musical notes represent the birth of jazz in New Orleans. The coin's third element, the outline of the Louisiana Purchase territory, refers to the largest single expansion of the United States, which roughly doubled the size of the country in 1803.
The obverse (heads) design features the familiar image of George Washington by John Flanagan, used on the quarter since 1932.
The reverse (tails) design features an image of the pelican - Louisiana's state bird - a trumpet with musical notes, and the outline of the Louisiana Purchase territory.
