Madame Marina Picasso, granddaughter of Pablo Picasso, will sell two paintings from her personal collection at Sotheby's Impressionist and Modern Art sale in Paris on June 6.

Created just one year after, this piece is exacted in a similar style to Guernica

Marina Picasso is a lifelong supporter of children's causes, and has established orphanages and programs in Vietnam using her grandfather's inheritance. As such, profits from the sale will benefit various noble causes, specifically those aiding children and adolescents in difficulty.

Offered in the sale will be Palette et Tete de Taureau, valued at $1.3m-1.9m, and Femme Assise en Robe Grise, estimated at $3.2m-4.5m.

Palette et Tete de Taureau was painted in 1938, just one year after the momentous Guernica - Picasso's fierce response to the atrocities of the Spanish civil war. The tension of Guernica is still present here, with similar motifs presented in the monochrome colour scheme.

Dora Maar was Picasso's lover and muse until she was replaced by Marie-Therese Walter

Femme Assise en Robe Grise depicts one of Pablo's most famous muses and lovers, Dora Maar, a French fashion photographer and artist. With Picasso attracted to the darker side of her character (including self-mutilation), this piece shows his "weeping woman" with dark rings around her eyes, "portrayed as a kind of black sphinx in an Elizabethan dress resembling a suit of armour", according to Sotheby's.

But you don't have to pay millions to own Picasso's work. We have this fantastic signed postcard of Picasso's Absinthe Drinker for sale.
