I just want a BLANK

I have been chasing prefixes for ALL the cards... but now, I think I'm settling into having an example of the "various prefixes"... and examples (in blanks if possible) of the "various" cards.

It's too much (for me) to chase down a billion cards everytime they change a phone number, add a partnership, switch machines, emboss, space, or delete a signature line

I am still working on getting the various "fronts"... and the various "backs" ...
and the various logos ON the backs of various fronts...

I wonder how much $$$ Harrah's spends a year on "abandoned product" everytime they deviate from whatever they JUST started!?

Bet it's a bunch!
