Mike - I agree, collect/catalog as you want. I collect by design, then by location number - one can't possibly know when you make a trade with someone just where that card was originally issued - history gets lost unless the original person puts a sticker on the back showing just where it was issued. The 2 Harrah's in Council Bluffs are the only ones with the Bluffs Run logo on the back. Those are not issued anywhere else. I think that because of the laws in Missouri, the Harrah's there must have a signature strip on the back of the cards.

I'm one of those crazy people who is trying to collect the different back variations for each design - that's a real chore and a heck of a lot of Harrah's cards. Kinda boring actually, except for the Elvis, Game of Life and Race car cards to spice up the collection.

Happy collecting !!
