Abstract: A display device for displaying ornamental electric lamps in windows or other framed structures, is described. The display device includes supporting rods which can be easily assembled and disassembled and inserted in a window frame. The supporting rods include compressible end cap means which allow the supporting rods to be adapted to fit snugly within a window, or other frame, without damaging the frame. The supporting rods further include rotatable interconnecting means for detachably engaging two or more of the supporting rods together to provide for forming a variety of configurations of the display device in the window.
