The Supreme Test Ever been on an ocean-going steam ship? Then you know what terrific strain and vibration the wall lining of the staterooms, dining-room, and saloons must stand. is the only material, except steel or wood panels, that can satisfactorily withstand this severe test. It is now used on several steamships in prefer ence to steel and wood. There's proof of the strength, durability, moisture-proofness, decorative adaptability, non warping, and non-shrinking qualities of Compo Board-the modem wall-lining. The reason is its wood-core construction. How important it is, then, that you look for and get the 'wood-core wall board when you ask for Compo-Board. Write for sample and interesting booklet.
