Abstract
Abstract A self-adjusting picture hanger having a wall mount member fixedly attached to the wall which rotatably coacts with a picture mount member secured to the rear of the picture. In one orientation, the members are free to rotate with each other so that the picture seeks and maintains a true vertical position. In a second orientation, a key on the wall mount member engages a notch on the picture mount member to fix the picture in a vertical position. The wall mount member is provided with notches which accept a plumb line for easily orienting the wall mount member.
