This is really a find! Only one other time have I seen this kind of vegetable (Oak) tanned bison. Most usually you cannot tool bison, or use for motorcycle saddles; gun holsters or the like. This is special; this you can!
I have not unrolled these sides yet ... so if you want a picture of the full thing let me know. They are 17-22 sq feet per side. 2 of each color in stock; more available for the moment from our "source".
