I should also consider if there are any well-known incidents from 1923 involving the phrase "Bank." For example, the 1923 hyperinflation in Germany's Weimar Republic. But would it connect to an individual named Jay? That seems unlikely. Alternatively, in the U.S., the Federal Reserve was established in 1913, and by 1923, they were still in early operations. There were debates about federal banking versus state banks.
