In your photo, there is an ad on the wall for "20 Grand Ale" which was named after the 1931 KY. Derby winner, 20 Grand. I remember a large neon sign for 20 Grand Ale, atop a building on W. Broadway in Louisville in the 40's to early 50's. TGT has the 333 Club listed as 1940's-1950's which sounds correct. However, TGT has the Copa Club listed at the same address in Newport as 1938-1961. I suspect that these dates may be in error.
