Abstract

A placard holding device for displaying a placard upon a vertical planar surface comprises a back frame member adapted for mounting upon the vertical planar surface and a front frame member having a flat surface portion enclosing an open window area. The front frame member is secured by a fastening assembly upon the back frame member. The fastening assembly includes a spacer member which holds the flat surface portion outwardly spaced from the back member and forms a placard holding pocket between the flat surface portion and the back frame member which is partially peripherally bounded by the spacer member. The portion of the pocket not bounded by the spacer member defines an access slot. An integral closure mechanism is provided which is operative for movement between an open position permitting passage of the placard through the access slot and a closed position preventing such passage. The device further includes an integral locking mechanism for maintaining the closure mechanism in the closed position while permitting selective movement of the closure mechanism from the closed to the open position.
