The ones made by Dave Whalen are all licensed Cat House chips. They are used in some form in the Cat House.
Advertising, gift shop, drinks, gift certificates, etc.

Bill Eichorn makes a lot of the un-licensed ones, but I'm sure others have jumped on the bandwagon.

I have a few including some of Whalens prototypes, usually 5 to 10 made.
I do not consider them fantasy chips. I consider them Cat House chips.
