The main typeface used for the exhibition graphics is the weirdly naïve Adultometric, “the mature version” of the earlier Infantometric. Latter is described as “part infantile, part geometric” by the foundry, CheapProFonts. I’m afraid the designer aimed for a “somewhat exotic” look here, but landed in almost cartoonish terrain. A nicer option from the same genre — condensed geometric sans — would have been Tomáš Brousil’s Ladislav (2013), which is based on the work of Ladislav Sutnar. Coincidentally, both Sutnar and Lindauer were born in Pilsen (today in the Czech Republic).
The wide sans used for the visitor information is the caps-only Idlewild — a fine display typeface, but ill-suited for anything more than a few words.
