Abstract: The overhead projector dry-erase accessory of this invention comprises a transparent, rigid, multi-layered body (12) into which overhead transparencies can be placed and utilized. The multiple layers of the device are created by either folding a single piece of transparent substrate in half, or by attaching two separate transparent plates at a single peripheral seam, with an adhesive strip 22. A transparent, dry-erase overlay (16) covers the top surface of the device, with the overlay being attached to the device at two opposing edges. A plurality of overlay spacer and attaching strips (18) both join the overlay (16) to the top plate of the device (14) and raise the overlay off of the top plate so as to create an air pocket for placement of tabbed or untabbed inserts therebetween. The attached edges of the overlay and the top plate of the device are protected, and the peripheral seams are further reinforced by a protective cap (20) placed over and further reinforcing them.
