I think this photograph could be interesting for you. This is my grandfather Julius Bondy with a Jewish company in either Karlsbad or Marienbad. I think it was a habit then to visit a spa.
My grandfather produced soda water; but it was rather his wife, Maria Bondyova, nee Buchwaldova, who ran the company, which was located on the main square in Holic. My grandparents weren't rich; they were middle class businessmen. Although they weren't rich they used to go to the spa in Karlsbad or Marienbad or Luhacovice; there were always many Jews there.
