Abstract: A hat display structure is shown to include an opaque substrate, a transparent layer connected to the substrate by snaps or the like at its edges, and a multi-piece frame, which, in turn, is snapped onto the layer. The transparent layer is formed to, in part, conform to the shape of an athletic hat or cap, with a bill, which has its crown folded in half, with the back half folded inwardly of the front half. Provision is also made in the layer for housing a plaque or the like in order designate or explain the significance of the hat or cap displayed.
