"Grun was insurpassable in capturing the insouciant spirit of the Paris cabaret; all his posters for the various places around town are among the best ever produced on the subject. This is a particularly fine, rare specimen for Cafe Riche, where, the text tells us, the smiling coquette is being escorted by the two gendarmes to see a piece called 'Au Violon.' One glance tells us everyone will have a terrific time"(Rennert, PAI-XXV, 330)

"Grun lived in the bohemian quarter of Paris and frequented its many cafes and bars. Trained in decorative arts, he started to design their interiors and stage decors and soon was also producing posters. His revellers express the very mood of the Parisian tenderloin, light-headed, with fun occupying every thought. The women especially exude an aura of charm with a hint of naughtiness that is Grun's own" (Gold p.104)
