Scan [I re-worked] from an eBay auction
Closest I can come is:

Lee On Card Room
Owner Lee On
614 Pine Street
San Francisco, CA
cira 1938

But chips from there are Hub mold and actual 'clay' chips.

The scan below is of a cardboard item and uses the hourglass mold. [Printed]

Any assistance would be appreciated as if confirmed I would like to include same in the second edition of my son's memorial project.

Wishing all enough,
