National Atlantic Washboard

This is a nice old washboard made from wood and glass. The glass is flat on one side and ridged on the other with the word NATIONAL embossed between each ridge. The best side reads Atlantic- No. 510 National Washboard Co., Chicago-Memphis. The other side reads the same but it is faded. There is a crack running about 5" long on the top. See pics. The washboard is 13" wide by 24" high.
