11506 Toulouse-Lautrec           Discovered 1990 Mar. 2 by E. W. Elst at the European Southern Observatory.
French painter Henri de Toulouse-Lautrec (1864-1901) helped set the course of avant-garde by using new kinds of subjects. A most significant work, painted with great psychological insight, is Elles (1896), a series of lithographs presenting a sensitive portrayal of brothel life.
