Email "The Master" Debby Meister.
A few weeks ago I spent hours trying to attach Ernest Hemmingways son to a 1937 chip in Ketchum, ID. I emailed her, she sent a link that nixed that idea in 7 minutes.

BTW, still researching the Ketchum chips and they are going to be good ones for illegal collectors. I have found two different books (with pictures} where Hemmingway says he loved to gamble in the place.
Thanks to Howdy Herz yesterday, I know have another name to research.
The best part is the chips were donated to a charity. Children will benefit from the sales of the chips.
