Abstract: A wall covering comprised of a plurality of panels formed with a stone and mortar design. The panels are mounted in horizontal courses with a lower marginal edge region of one panel being in overlying relation to the upper marginal edge region of a panel in a previously mounted course. The upper and lower marginal edge regions have a tapered seating design which enable close positioning of the stone and mortar of two mating panels with the mortar lines between the stone being in substantially coplanar relation with each other and where a portion of the simulated stone protrudes downward in different locations so as to create a non-uniform mortar distance between simulates stones on an upper panel from simulated stones on a lower panel, thus further obscuring the seam formed between the panels.
