Abstract: A mirror arrangement having two parallel side walls 2, a front wall 3 with semireflecting mirror and a rear wall 4 creates an improved visual effect by arranging the front wall 3 and the rear wall 4 non-parallel to each other. The base of the compartment enclosed by the walls 2, 3 and 4 is thus trapezoid, and between the front and rear walls 3, 4 and an adjoining side wall 2 an acute angle .alpha. is defined which does not exceed 85.degree.. The walls 2, 3 and 4 are secured to a frame 9 of square tubes 10. Several showcases 1 composed of the walls 2, 3 and 4 and the frame 9 can be joined together in any number and design at any size through modular assembling. In the showcases, a number of juxtaposed mirror images of the objects, which are exhibited in the showcases, are generated along a primary path which is flanked by further, in some cases opposingly arched paths so as to allow viewing of the objects from all sides.
