A fastener for hanging an object such as a picture, or a plaque, on a vertical surface such as a wall of plaster or wallboard is formed by attaching a narrow flat strip of metal to a small piece of sheet metal so as to project outwardly at right angles to the small sheet, the ends of the strip being sharpened to provide prongs to be inserted respectively into the wood frame of the object to be hung and into the wall. The side of the small sheet facing the wall is covered with a sheet of partially delaminated paper, or similar material, which is coated on its exposed surface with a soluble adhesive which is moistened at the time of use to cause the fastener to adhere to the wall. The fastener can be withdrawn by completing the delamination of the paper and soaking the residue on the wall with liquid.
