From a great Berlin exhibition that revolves around the Whole Earth Catalog and its impact. It looks a lot like Nick Shinn's Figgins Sans to me, but it's different in some (obvious) details: ascender-to-cap ratio, the t, the, r, the f... Maybe custom modifications?
PS: for »Figgins Sans« in the above post, we may also substitue Klim's Founders Grotesk: close, but not quite...
Thanks for posting this.
I quite like the way the tail in the /a/ gets cut off in the first picture.
Odd the way the tail on the /t/ sharpens as it comes out, much like the a here
