An apparatus for marking on a wall the position at which one or more fastener devices are to be installed for the hanging of one or more pictures or other objects, the marking apparatus comprising:

• one or more first extension portions connected to and extending from an attachment element that is attachable to an elongate frame that is comprised of a straight bottom edge, a rear face and a front face;
• and
• one or more adjustable second extension portions connected to and extending from each first extension portion, wherein each such second extension portion is in a plane substantially perpendicular to the first extension portion, is extendable to varying lengths as measured from the first extension portion and has one end that is comprised of a hook element that extends away from the attachment element and a marking element that extends towards the attachment element,
• wherein the elongate frame to which the one or more first extension portions is attachable is placed rear face down on a floor or other horizontal surface with one or more pictures or other objects to be hung also positioned on the horizontal surface, face down and with their top edge abutted against the straight bottom edge of the elongate frame,
• wherein the positioning of the first extension portion can be adjusted to allow the hook element at the end of the second extension portion to be extended directly toward a hanging element on the back of the one or more objects to be hung,
• wherein the hook element of the one or more second extension portions is inserted into each hanging element on the back of the one or more objects to be hung,
• wherein the hook element of each second extension is disengaged from the hanging element into which it is inserted and the marking apparatus is picked up from the horizontal surface, rotated end-over-end and positioned against the wall with its front face towards the wall and the first extension portions against the wall, and
• wherein the marking element on each extended second extension is pressed against the wall leaving a mark on the wall at the spot where each of the one more fastener devices is to be installed.
