The flag holder includes a plate surrounded by an edge flange. Raised letters and symbols are integral with a plate face side. Letters, symbols and edge flange have flat surfaces in a front plane. The plate has a rear side and three mounting bosses with rear surfaces and threaded bores. Surfaces of the edge flange and the bosses are in a rear plane parallel to the front plane and the plate front side. Two vertically spaced tongue members extend from an outside surface of the edge flange. A U-shaped flag pole recess in each tongue has an open end that faces rearward. Three threaded pins are received in the threaded bores. Epoxy holds the pins in gravestone bores. Flag pole recesses are closed by the gravestone. A pole support surface is on the edge flange.
