Glas-Hertel is a family-owned glass company founded by Karl Hertel in Düsseldorf in 1869, as Königlich-Sächsische Hofglasmalerei. In 1928, one branch was relocated to Lippstadt, which is still in business today as Glaserei Hertel. The workshop located at Benzenbergstraße 35 in Düsseldorf-Unterbilk is permanently closed as of 2025.
The sign above the doorway features Ramona. Designed by Henry R. Möller, this all-caps slab with bracketed serifs was first cast by Schriftguss in Dresden in 1939. Its open, squarish letterforms are a good fit for a company dealing with panes of glass. The green multiline G to the right is the symbol of the German glaziers’ guild.
