The MG inlaid chips were manufactured by USPC in 1928 and delivered to Boise, ID.

These chips originated from an estate sale of a family that lived in McCall until 1951 before moving to WA (where they continued running gambling operations along with Ida Carl Forbis and family). The grand-daughter had researched this in the past, and from pictures believed that the building used was either the Payette Lakes Inn on page 12 of this link, or a similar building that perhaps burnt down as many did in that time.

She also noted that at that time, when much of the town was virtually a continuous landscape garden, it was known to outsiders as McCall Garden. At that time McCall was an exclusive weekend gambling retreat for Boise residents with a history of gambling and pro$titution.
