Take this as only a vague vague memory. Long before I was into chipping, I made many trips to Vegas. I do remember the Wizard of Oz store in the MGM and this is where it gets cloudy ---I think they sold these chips in there as a set. The set had the different characters from the movie on them.

Somebody please help clear this up. I am even relutant to post this as it is so vague to me. Hope this may trigger some one else's memory.
