Minimal info on record Mason card.

Val Bumgarner
Medicine Bow, WY

1937 – 2000 chips, basically 100 each of every color Mason made.
First thing that went through my mind on these was salesman or reseller.

In the later 1930s Val Bumgarner was working and living on George Fagen's ranch in Medicine Bow, Wyoming. He gave his job as "utilities" on the ranch and is listed along with a few others who were "ranch hands". I could find no mention of gambling.
