Abstract
A plurality of elongated opaque holders with elongated openings therein are removably connected together at their longitudinal edges by light excluding joints, there being a light source behind the interconnected holders. Opaque strips bearing translucent indicia are removably connected to the holders over the openings. The indicia may specify items of merchandise. Pre-curled plastic film tapes bearing numbers are movably mounted at one end of each opaque strip to display the price for the item. The pre-curled tapes are mounted behind holder portions having window openings through which the numbers are visible and through which the pre-curled tapes can be manually contacted to conveniently change the prices.
