Hi - I just talked with my Dad - David Baltes. His dad, Norbert Baltes sent my dad down to Chicago to visit a Tony Baltes who used to haul coal up to second story apartments, etc. He thinks that was around 1935-1940 as he recalls. My dad still wears a cameo ring that his dad got from Tony as collateral for a $20 loan, but was never repaid. Hope that helps.
