Abstract
Abstract A reproduction in castable material of a photo or other form of picture and a method of producing the cast picture. A photo or other desired form of scene is reproduced as a black and white negative with shading eliminated, and the negative is processed to produce a likeness thereof in the castable material with the dark lines standing in relief and the light areas recessed. The recessed areas are filled with powdered enamel to a level somewhat below the top of the relief features, and the object is baked to fuse the enamel and bond it to the casting.
