The flag of the state of Wyoming consists of the silhouette of an American Bison. The red symbolizes the Native Americans and the blood of pioneers who gave their lives. The white is a symbol of purity and uprightness. The blue is the color of the skies and distant mountains. It is also a symbol of fidelity, justice and virility. The bison represents the local fauna while the seal on it symbolizes the custom of branding livestock.
In 1916 the Wyoming Daughters of the American Revolution (DAR) ran a contest inviting the public to submit possible designs for a Wyoming flag. A prize of $20 was offered to the winner, and the DAR received a total of 37 entries. They chose a drawing by Verna Keays, a recent graduate of the Art Institute of Chicago. On January 31, 1917, Governor Robert D. Carey signed the state flag bill into law and the bison flag was officially adopted.
