Adopted in 1925. New Mexico became the 47th US state in 1912. The first state flag of New Mexico was a blue field with a miniature United States flag in the upper left corner, the state's great seal in the lower right corner and "New Mexico" embroidered diagonally across the field from the lower left to the upper right corner. In 1920, the New Mexico Chapter of the Daughters of the American Revolution advocated the adoption of a flag representative of New Mexico's unique character. Three years later, the D.A.R. conducted a design competition, won by the distinguished Santa Fe physician and archeologist, Dr. Harry Mera. The doctor's wife, Reba, made the winning flag design with a symbolic red Zia on a field of yellow. In March of 1925, Governor Arthur T. Hannett signed the legislation, which proclaimed the Mera design as the official state flag.
