TSR released some cards in the early 90s, not a game but sets of cards. IIRC there were 3 sets of about 750 cards each. For a while after they were released in packs you could buy whole sets in tins, which you might be able to find on Ebay or something.
One of the cards of the first two sets, I'm not sure which, was the Ring of Winter. There's artwork on the front and a lot of text on the back, which I don't remember except that the ring was said to grant the wearer immortality.
If that sounds accurate for the Ring of Winter, it might be worth tracking down a set (I think they go for about $20), but if it sounds made up then it probably was. A lot of the cards were cropped artwork from pieces by Brom, et al., with names and stories invented for scenery characters.
