Abstract
A drafting board having a planar top surface with a peripheral depression. A thin, resilient, cover sheet is removably secured to the top surface by a pressure-sensitive adhesive and extends into the peripheral depression where it is retained by a peripheral retaining rim extending about the panel below the plane of the working surface. The parts are structurally related so that the cover sheet slopes gradually downwardly into the depression without lifting or bulging along the outer limits of the panel's top surface. Replacement of the cover sheet is achieved by removing the retaining rim, stripping away the old cover sheet, adhesively securing a replacement cover sheet, and securing its border within the depression by re-mounting the retaining rim.
