Abstract: A board and plaques detachably securable thereto. The plaques are miniaturized versions of packaged merchandise as viewed from the front. The board is imprinted with two-dimensional miniaturized representations of shelves and/or partitions marking off shelf sections. The plaques are temporarily positioned on the board in a selected layout in simulation of full sized displays of the merchandise in order to facilitate stocking the shelves and/or re-arranging the shelves and/or vertical partitions. The board includes a laminar ferromagnetic panel and the plaques include magnets. Alternatively, a disruptible adhesive may be used to attach the plaques to the panel.
