It will still need some sanding to get a perfect smooth surface but it is almost perfectly flat and fairly smooth. There is a very small amount of cupping on the wider side.It is just the bark and edge curling up a bit. The side with more bark view is flat. It is approx 15-17 inches wide throughout the length. It is approx 52 inches long. It is 1 1/2 inch thick. The photos show both sides.
There is one missing section 7 inches long on one edge. There are some drying cracks, see photos.
It was misted with water to help show the finished color in some of the photos. These are beautiful rustic pieces with occasional chips, cracks, frayed edges, insect holes and trails, etc. I always give multiple pictures and a detailed description, so you know exactly what your going to get. Let me know if you have any questions or need more photos. This item is made of black walnut.
