Here is a coroplast real estate sign mounted to a brick facade. The sign is 3′ x 4′ and because its coroplast and the graphics are screen printed.
For this job we made 1/4″ thick white acrylic dimensional letters pin mounted above the entrance in the painted wood. The letters are 3.5″ tall and are about 60″ wide. The white color of the letters really contrast well with the dark color of the paint on the background.
