Thimble Clubs found as early as 1903; more popular in 1930s

I did some digging and found that the "Thimble Club" was not a Paul Rhymer invention, as they can be found planning to congregate (in newspapers) as early as 1903.

However, by 1932, the same year as Vic and Sade began, you see a large uptick in mentions of club meetings in newspapers.
