ABSTRACT:
A display board for displaying a menu of daily fare for restaurants, post exchanges, and the like, wherein the items listed for sale are printed on a long thin flexible plastic strip located in tracks that extend substantially the full width of the display board. The prices for the items listed are printed on a much shorter plastic strip which may be changed instantly and independently of the item strip. Both strips include a smaller width strip of iron ink on their back side, so that both strips are held in place by the same flexible magnetic source strip that is imbedded in the display board in parallel fashion to the display board tracks wherein the plastic strips reside. A clear plastic cover is locked in place over the finished menu to retain the displayed menu and prices until a change in fare is desired, at which time this cover is instantly removable.
