The Red Star Line employed the leading companies of the day to print and publish their postcards. By 1900 the finest images were being printed using the process of chromolithography and all the early
RSL sets were produced by this method.
The list of printers of the RSL art cards is impressive :-
- O.de Rycker Brussels
- O.de Rycker & Mendel Brussels
- Dietrich & Co Brussels
- Fritz Schneller Nurnberg
- J.E.Buschmann Antwerp
- Muhlmeister & Johler Hamburg
- E.Stockmans & Co. Antwerp
- J.L.Goffart Brussels
- American Litho Co. New York
- J.E.Goossens Brussels
The majority of the Cassiers cards came from two of these. Dietrich were responsible for his watercolours of landscapes, coastal scenes and city scenes while his graphic art nouveau seascapes, for which he was most famous, were printed by de Rycker & Mendel.
