to the canvas. During World War I (1914-1918) he worked in Paris
he had his first one-man exhibition in Paris in 1919. From 1922
to 1924 he designed settings for two ballets of the Russian producer
Sergey Diaghilev, Les tentations de la bergère (The Temptations
of the Shepherdess) and La colombe (The Dove), as well as continuing
work on his own paintings. After 1925 he worked mainly on gouaches,
watercolors, and illustrations for books.
Some of his famous works include Portait of Josee, The Table and
The Open window. Portrait of Josette was created in 1916 and is
now in the Musea del in Prado, Madrid. This was definitly one
of Gris's greatest achievements. The portrait of Josette is based
on his studies after Corot and Cezanne. To perfection he seemed
to create a stunning mixture of the foreground and the background.
