Patent attributes
A wall covering comprising a plurality of panels each formed with a plurality of horizontal rows of simulated building elements, such as hand laid stone separated by simulated lines of mortar. The panels have side marginal edge regions formed with hooks and side opening slots that are interengageable as an incident to relative lateral movement of the side marginal edge regions during installation, with the rows of simulated building elements in one panel, being drawn into aligned and predetermined spaced relation to the rows of building elements and adjacently mounted panel. The underlying side marginal edge region of each panel is formed with a non-planar undulating surface similar to the mortar lines throughout the panel, and the overlying side marginal edge region of each panel further is formed with a complementary undulating surface for tight mounted positioning onto the undulating surface of the underlying side marginal edge region.
