Hi Steven,

Thanks for ther reply. I'm glad you found it interesting.

I had some free time this morning and it was fun to put together. I have a dozen or so more variations...if there is interest, I'll scan and post some more (I added a Harrah's color variation to this post).

I'm still curious to hear if there is a definitive word on what is and is not a variation and if there a difinitive word, who decides.

I think it is up to the individual collectors discretion.
