The 13-cent West Virginia State Flag stamp (Scott 1667) features an image of the West Virginia state flag.
Adopted in 1929, the flag of West Virginia displays the state's coat-of-arms centered on a white field. The date of admission to the Union—June 20, 1863—is etched on a stone, and the state motto—"Montani Semper Liberi" (“Mountaineers Always Freemen”)—is printed on a ribbon below the farmer and the miner.
A red ribbon floats above the coat-of-arms bearing the words "State of West Virginia." Wreathed rhododendron, the state flower, is arranged below the coat-of-arms. The pure white field is bordered in blue on all four sides.
