Yesterday I went to visit my old Philosophy Department, and I saw this poster on one of the professor's doors (bearing the title "Mathematical Logic and Foundations 1847-1947" and crediting Joel Friedman as its author, and providing 1976 as the creation year), and I felt that I have to share it on Mastodon (if nothing else, then just for the sake of writing alt text ;D)

It's around 3MB, so sorry about that, but I didn't want it to reduce it to make sure the letters remain legible.

I also found this write-up about the poster: https://dailynous.com/2014/10/28/mathematical-logic-foundations-chart/
