C Malcuit / M Cosson, Paris

The Bottin entries are for Malcuit himself (1909), Jorel a successor (1911), and M Cosson (1914 and 1925) - another with links back to Malcuit and still using the CM logo. All 3 operated from the same address.

Malcuit view cards have C.M. printed at the end of a title on the picture side, and sometimes Malcuit named on the address side. The first example card is of different subject, it predates the directory entries and uses the logo CM Paris but is presumably a Malcuit card. Cosson view cards also have C.M. printed at the end of a title on the picture side, and Editions Cosson named on the address side. Jorel seems to have produced more topic cards, he has a separate entry here as he also produced cards without the CM logo. All his cards seem to also include his name.
