I've never seen one like this before. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1315&item=7130047729&rd=1
I saw these a month or two ago when the whole box of like 100 was for sale for a couple of hundred dollars. My guess is they were mis-spelled (there is no space between Wild and Cat) so the customer never claimed them, and were pushed in a back room. 20-40 years later someone finds them, and volia, eBay time. I would love one, but can't stand the space in the spelling.
