Stabilimento Grafico Césare Capello was a printing company founded in 1908 by Césare Capello in Milan at 7, via Lazzaro Papi. It lasted until the 1980s when the brands were bought by another company and used for other stationery products. There is an article on Cecami in the Italian Wikipedia but it is very short and rather incomplete.
The firm printed material aimed at tourists, eg guides, maps and accordion-folded picture brochures as well as postcards. Later view cards are identified explicitly, The Cecami logo is used on view and figurative cards from around the late 1930s to more modern times.
Cecami 1023 is a bit later than the target of ths site, but is interesting to compare with the many examples of WW1 cards here.
