The Wyoming State Flag, designed by Mrs. A.C. Keyes of Casper (formerly Miss Verna Keays of Buffalo), was adopted by the fourteenth
legislature on January 31, 1917.
The Great Seal of Wyoming is the heart of the flag. On the bison, once the monarch of the plains, is the seal representing the custom
of branding. The colors of the State Flag are the same as those of the National Flag. The red border represents the Indian and the blood
of the pioneers who gave their lives reclaiming the soil. White is the emblem of purity and uprightness. Blue, the color of the sky
and mountains, is symbolic of fidelity, justice and virility.
