Black Walnut Slabs

Here are pix of the black walnut slabs we have which await purposing in a friend's basement.  They are 54" long and approx 16" wide and 5/4" or 6/4" thick.  Two have the live front edge on the sapwood and one has a clean cut front edge.  
The color is much yellower in these pix than they really are - bad lighting.
