Abstract
Dry-erase drawing sheets, a drawing apparatus, and a dry-erase drawing kit are described. The drawing sheets have a non-lenticular or a lenticular lens arrangement on a top surface, material layers comprising a body of the sheet, and images printed on surfaces of one or more of the material layers. The images are configured to sufficiently interact with the lens arrangement to exhibit a three-dimensional visual and/or animated effect when viewed through the top surface. The drawing sheets also include a dry-erase compatible layer overlying the top surface. The drawing apparatus includes a frame that has a central opening and a backing member that releasably couples to the frame. Together the frame and backing member retain the drawing sheets within the central opening of the frame during use. The drawing sheets, drawing apparatus, and one or more dry-erase crayons or markers are provided in the kit.
