Jan Tschichold

Here’s another cool poster I found breaking down letters, this one is by Jan Tschichold. Just like the Baskerville poster I found a while back, I think this one excellently represents how letters are formed from basic circles and lines. I’m not sure what typeface this is but I would assume it’s an old style serif because it’s very classical-looking, is obviously a serif, and there is not significant contrast in the thickness and thinness of the letterforms.
