Abstract: A wall positioning device comprising a mounting set for hanging a display board, or picture, or the like, from a wall or other vertical surface support, wherein the display board or picture is assured to be hung straight and level, and yet may be easily removed or replaced by another board having a matching hanger piece, whereby the second hung picture will a also be straight and level. The technique used in this hanger mounting set involves a projecting tab on the hanger piece a attached to the board or picture, and a receiving notch on the other hanger piece that is attached to the wall, wherein each of the two pieces incorporates a small spirit level that may remain permanently as a part of that piece, or be removed after installation as desired. The matching notch and tab are each located on horizontal members that engage simultaneously with said notch and tab, and prevent any angularity in their engagement, once the tab engages the notch.

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.
