Rare piece of corrugated glass. It measures approximately 50" x 54" and is 3/8 inch thick. Very heavy. This type of glass was produced in the 1920's through the 1940's. Came out of an interior wall of a home built in 1948. I have no use for it. Would be great for an interior space remodel. I do not know if it is tempered or not, but would guess it is not. Asking $250 cash or best offer. Message here if interested. Thanks!
