Abstract
A pressure sensitive reusable writing board is provided which includes a backing layer printed with a background color and coated with wax and a single polyester sheet attached to a wax-free strip of the backing and which overlies the wax layer. Pressure applied to a front surface of the polyester sheet causes the sheet to cling to the wax layer thereby showing the writing as a dark color (i.e., the color of the wax) on a white or light background. The white or light background is provided by printing on the undersurface of the polyester sheet with a white opaque finish. Graphics, such as lines, maps or other educational or functional graphics may be disposed on the undersurface of the sheet. The backing may also be mounted onto a larger panel which may include additional informational or decorative graphic presentations.
