The Moulin Rouge
The Moulin Rouge still exists, and still attracts visitors to see their cancan dancers. This is the English-language Web page. I imagine it might read smoother if you could read it in French.
San Diego Museum
A very useful and informative resource. It features many photos and reproductions of Lautrec's paintings, plus biographical information on Lautrec and his subjects.
"A visual exploration of Toulouse-Lautrec's most famous lithograph (Aristide Bruant: Ambassadeurs)." This site features biographical information about Lautrec and Bruant, plus an animated tour of the process that went into creating this six-color poster.
City of Albi
The Web site of the city of Albi in the south of France, where Toulouse-Lautrec was born. Among other attractions, they boast a Lautrec museum. Unfortunately their pages on Lautrec and the museum are in French. To have them (or anything else) crudely translated, you might want to try http://world.altavista.com/.
Toulouse-Lautrec and Belle Epoque France
A page for an art history class at the University of Colorado. This great resource includes dozens of images — photos and high resolution scans — of Lautrec's art.
