Abstract: A picture position marking tool comprises an arm having an element for marking a position on a wall, as by penetration of the wall. The arm supports a picture either by a wire hanger or a strap hanger, so that the hanger is in substantially horizontal alignment with the wall marking element. A protrusion may be provided on the arm, located on the same side as the marking element, and spaced from it. A handle is provided which includes a grip portion which, in a preferred embodiment, is connected to the arm by a connecting portion, the connecting portion being at right angles to both the arm and the grip portion and providing a tool of generally U-shaped configuration. The handle portion may also be, in other embodiments, in other orientations relative to the connecting portion. In still other embodiments, the handle portion may extend directly to the arm, spaced from the marking element and forming an angle with the arm: the angle may be either a right angle, or an acute or obtuse angle.
