Display adapter for signboard
 A display device hooked to a signboard comprises a placard and a connecting member fixed to the signboard for hooking the placard which is provided with a L-shaped slot extending from the upper edge of the placard. The connecting member is characterized by a forwardly projecting stem adjacent one edge and an abutment member forwardly projecting from the signboard and located below the stem and further remote from the lateral edge which is adjacent the stem. The L-shape slot in the placard is adapted to engage the stem while the placard is in a tilted position and the abutment member is adapted to abut on the above-mentioned edge when the placard is pivoted in a vertical position.
