90 Topps Traded FB Card Stock

Can someone tell me what kind of card stock 1990 Topps Traded football is on? In order to fill a glaring hole in my collection, I jumped on ebay and bought the Emmitt from that set. I didn't any shopping around for this card because it is pretty cheap, and bought the first one that I came across. When the card came in today, it was on pure white card stock. I know the regular 90 Topps are on brown stock, but was not sure about the traded set. Everything else about the card seems ok as far as I can tell - no "dotty printing" or anything, but the card seems too perfect. Anyway, I wanted to do my homework first before I accused the seller of a fake, so I thought I would ask you guys. I'm not too worried about the few dollars I spend on the card, but it's the principle of the thing. TIA
