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.
