I’m not sure this is the right spot for this but I think y’all would know best. I got this at an estate sale, it was in a bag labeled 1980’s custom. I want to see if it is A.) easy to clean the stains, I think they may be old dog pee. B.) Worth anything and C.) more about the makers mark. The only thing that came up was an Alpaca skin rug for what seemed like way too much money. It’s also big, about 8’ by 4.5’
