RULES OF GAMES
I came upon this site and much to my surprise the images on the cards aren't familiar to me. I will try to track down the origin of the cards. Have a look.

I went to the site - it is an information only (of rules) for different games. I am just suspecting here - but maybe the web site has to have a "unique" card deck so that they do not infringe on copyright rules by using some existing card deck. Just a thought. But, I imagine that you would have a lot better handle on something like that - let me know your thoughts. Richard
Maybe. In any case I forwarded the material to US Games Systems and they can follow up on it if they see fit.
