It includes a solid object having predetermined dimensions and at least one planar upper surface. The planar surface has a plurality of slots extending fully across the planar surface. The slots have a width and depth suitable for holding a substantially self-supporting flat object at a substantially vertical orientation with regard to gravity. It also include a support to raise the planar surface at an incline, preferably from 5.degree. to 30.degree. from the horizontal. A plurality of these display devices can be connected to each other or juxtaposed, in modular fashion, along their sides or portions thereof.
