A product information and display tag has a mounting portion particularly designed for use in attaching the tag to a flip lock-type elongate product display hook. The mounting portion of the tag has panels which can be folded into a wedge-like configuration to be trapped between a pivotal hook bracket and an apertured board when mounting prongs on the bracket are inserted through adjacent board apertures. The respective panels forming the wedge are provided with aligned apertures for receipt of the hook prongs and a cut-out is provided at the top of a front panel for accommodating the top shoulder of the hook when attaching the structure to the apertured board.
