These 6" designs are on 2' x 4' tiles. The designs vary from Art Deco to Victorian and Americana to Turn of the Century. The material is Tin-Plated Steel and has great paint retention with an oil-based paint or you can urethan or lacquer them (also oil-based) to keep the shiny silver finish. They have been used in kitchens, diningrooms, bedrooms, hallways, bathrooms and game rooms. They are used on ceilings, walls, as wainscotting and as backsplashes. Cost is 2.25 a sq.ft. Slightly higher for use in a suspended ceiling.
