Steve,
Great info, especially about the Dallas chip. That is quite a find because Ivy Miller was a junior partner of Benny Binion and Harry Urban in what was known as the Southland Hotel Group. In 1939 or 1940, Miller and Binion ambushed Sam Murray, another top Dallas gambler. Miller was indicted, but the indictment was dismissed for lack of evidence.
Cheers,
Russ
