A placard frame comprises a first frame member and a second frame member spaced from the first frame member and extending therefrom at a margin, wherein the first and second frame members and the margin define an interior space adapted to receive a placard. A projection is disposed on one of the first frame member and the second frame member at a location one of at and adjacent to the margin wherein the projection extends into the interior space. Further, a slot is in communication with the interior space.
