I got this in 1995 in England at Harrods in London. It’s been used once and other than that been in storage it’s like plastic clear waterproof sturdy. Somewhere on one side where I think a magazine or newspaper got stuck to it. I am afraid to clean it or try and get it off because I don’t want to damage it it is be ing sold as is and price will reflect the discolorations. SEE PHOTOS zoom in to last photo to see discoloration
