1/2In X 3ft4in X 1Ft7in Plywood Wood Working Panel From 150year Old Walnut Tree. The back of board dose have water marks from milling but that will sand off and is why the back looks so dirty. We do wipe our boards off now and clean them after milling and before drying. This was just one of our early cuts when we were getting started. One end of the board does have a slight bow(SEE PHOTOs).
