Well a long awaited mailday today, received a complete set of the 1997 Superleague cards from a member of OCT (thanks Steven). Feels nice to get something that you have been trying to find for a while.
Here is a scan of two of the gate cards, front of the Rams and the rear of the Mariners (these are spare gate cards and are available for trade / sale).
I will scan a couple of the other cards now and upload them in a few minutes; done and here is the header card, COA, promo and an example of the first lot of the chase cards.
