PSFS versus Glendale Federal

Howe and Lescaze's PSFS tower [1932] in Philadelphia has made it into the canon of great buildings as the first International Style skyscraper.

I've always been a huge fan of PSFS, but I'm also a great fan of the Glendale Federal Savings building from 1959.   It has functioning adjustable louvers to provide shade, bold use of color, and the building has always reminded me in some way of PSFS.
