does anyone else remember or have pictures of large plastic wall murals for crayons ? i have some memories of coloring these after they were hanging on a wall in my bedroom , if i remember they were designed to wipe the crayon off for a clean coloring mural , they were prob 4 ft by 4 ft ? but as a kid they might have seemed larger , im sure that once we colored them we threw them away . it seems like i remember for some reason that we bought them from a door to door salesman ?they were just white plastic with black pictures like a coloring book . and i think we just taped them to the wall to color them ?
