My regular copy of Norton, and my solitary Bishop.
Tom's Flickr album is awesome and the Norton is made easier by the red grass blob on it, but to my eyes both Norton's are purple skies - there just wasn't a fully corrected copy. I've never seen a Norton that looks to me like a fully corrected blue sky card.
Bishop I am not certain which on I have here and identifying off eBay or at shows which is which I've never succeeded at. Do I need a card for a master set if I can't tell the difference? The answer is yes, I need it anyways

This has become my favorite football set of the 60's.
