A menu board system comprising a support structure, made of magnetically attractable material, and various strips indicating, for instance, products sold and magnetic elements indicating prices at which products are sold. Once all the elements and strips are in place on the support structure, the front surface of the menu board seems flat and continuous as all pieces are cut to fit perfectly in an edge-to-edge pattern. The price elements are easily removed by simply pressing an element's bottom portion allowing the top portion to lift off the support structure. The ease of removal is caused by a magnet fixed only to the top portion of the back surface of the price element. The bottom edge of the magnet acts as a fulcrum point and the back surface of the element left uncovered is simply pushed into the support structure, permitting the top portion of the element to be grasped.
