Abstract

A rectangular sheet of backing material has a first surface and a second surface and a conductive wire which is mechanically coupled to the first surface of the rectangular sheet of backing material. A work of art includes a decorative frame and a stretcher frame which has a first surface and a second surface and which has a rim disposed on its first surface along its peripheral edge and a painting canvas which has a front side and a back side. The stretcher frame includes a plurality of individual frame members which permit each of four peripheral edges of the front side of the painting canvas to be folded over so that the folded over peripheral edge is adjacent to the back side of the painting canvas. The dimensions of the stretcher frame may be expanded in order to stretch the painting canvas. The stretcher frame and the painting canvas are mounted on the decorative frame. A plurality of staples secure the conductive wire to the painting canvas, the stretcher frame and the decorative frame. The second surface of the rectangular sheet of backing material is disposed adjacent to the back side of the painting canvas. The conductive wire is electrically coupled to an alarm transmitter and a tamper switch which are disposed within the decorative frame.
