An alphabet designed by Georges Lemmen and shown in Petzendorfers Schriftenatlas as Georges-Lemmen-Schrift, with a full set of caps (incl. alternates for ‘DELPR’), lowercase characters and numerals. [Petzendorfer 1905] It’s not clear if it was produced as foundry type.

Berthold made it in into a phototypeface named Georges Lemon [sic!]. [Berthold 1974]

Digitizations by Richard William Mueller as Argos (1993) and by Dieter Steffmann as Argos George (1999, used for sample) – the word “Argos” is included in the Petzendorfer sample text.
