Guillaume Becker, later Marcel Bernheim, Paris

Guillaume Becker, then Marcel Bernheim of Paris owned the GB marque up to 1907 (see directory entries). Bernheim's directory entry shrunk to just his address in 1909. By the time of WW1 cards with the sloping GB logo with the swirl below appear. Some, including the one here, name Artige & Cie as the publisher or printer. These marques may be unconnected. It is also possible that GB and GB Paris logos on the two undivided cards represent different publishers, though both must have been in Paris.
