Ad for Paul Braess, a furnishing house in Düsseldorf, Germany, from 1906. The all-caps typeface was carried by numerous foundries, under different names. Its origin is unclear. Chances are it’s one of the designs that originated at a company like Wagner & Schmidt or Riegerl & Weißenborn, which produced matrices and sold them to various foundries.
