This original lithograph, Jeune Femme au Corsage à Triangles, 18.5.1947 (Young woman with the blouse with triangles) was created May 18, 1947.  It is one of three similar portraits he made between May and June of that year.

At this time Picasso was with Francoise Gilot (since 1943).  This is the first work of art Picasso created after the May 15th birth of their son Claude!  More geneological detail is here.

The lithograph was made by Picasso drawing with a wash and gouache and crayon on lithographic paper, and then that image was transferred to a lithographic stone for printing. 

It was printed by Mourlot in a limited edition of 50 examples plus five artist proofs.  This is one of the five artist proofs.

Mourlot was the famed printer at whose studio Picasso spent much time learning and experimenting with the lithographic medium since 1945.  In the next quarter century Picasso had created more than 800 lithographic images. 

Norton Simon purchased more than 220 of Mourlot's Picasso lithographs in 1977.
