Henri de Toulouse-Lautrec, once the primary witness to Montmartre’s golden age, well knew like a fan and patron of cabarets and brothels, and depicted his dissolute life and his surroundings swiftly and caricatured.

Post-Impressionist French painter will be on display in the Grand Palais in Paris in a special retrospective, "Toulouse-Lautrec, Resolutely Modern." Mentored first by Princteau, Bonnat and Cormon, and later by Manet, Degas and Forain, Toulouse-Lautrec had two distinct periods: one of naturalism and another more caustic.
