Ive been working on this for a while, though they are tough to find. Issued in the mid-50s, the most collectible set nationally is the Kentucky set featuring Adolf Rupp...Ashland Oil did several sets of regional schools. I guess you got them with a fill up...anyone remember? You gotta love the Cam Henderson card, the key to the set. Hey, if you've got any extras, zap me an e-mail. I might have an extra Henderson to dangle....
