(11506) Toulouse-Lautrec Main-belt Asteroid

Discovered on 2 March 1990 by E. W. Elst at La Silla.

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.Naming citation (20000523/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
