I got a couple sets of these yesterday in the mail (the reverse side is common & it is the Coop Devil smoking a cigar).
I will post a pic of the reverse sides as a reply to this message.

I some collect some Coop art and I have a different Coop Chip Set that I got from Coop Stuff.

I wanted to post these to show them off and in case, someone else may be interested in adding this set to their collection.

They are on ebay (not my auction) ... heres a link:
