ABSTRACT OF THE DISCLOSURE The process of displaying indicia on a panel includes forming a panel with a substratum of a first selected material and at least one superstratum of a second contrasting material attached to the substratum. At least the superstratum is meltable, and preferably both material layers are formed of tough, pliable, weatherproof plastic such as polyurethane. A heated indicia-forming tool is pressurally applied selectively to the superstratum to melt localized portions of its material throughout its thickness and force it out of the path of movement of the tool, leaving corresponding portions of the substratum exposed to define indicia with a contrasting background.
