Original 70's or 80's Adidas Bag.  Not sure if it is real leather or not, but I would be surprised if it is faux leather with its condition.  It was my fathers bag. I remember seeing him carrying it around in the 80's, so I know its authentic from way back!  Not sure exact year of manufacture though. 1 small hole on side wall and a couple minor tears on the back(seen in last two photos). Fair condition for age.  Original zipper works perfectly.
