CHAISSAC Gaston (1910-1964) Signed autograph letter addressed to Pierre GIRAUD illustrated with original drawings S.l.n.d., 4 pages in-8 in violet ink, one of them with the address of Pierre Giraud enchanting in the cellar in Limoges. (Slight lack of paper without affectation to the text). Chaissac gives Giraud his definition of Art Brut: "Art brut, the "spoiled child of the season" that it is, cannot indefinitely fill your life and make your fame resound and you may decorate your canvas with stumps, but that is not what will make you deserve the country". He mentions Drouin and Dubuffet. "You can't achieve mastery without being an apprentice and a journeyman. I see you on the way to becoming one day an old, old-fashioned and ridiculous gentleman and I take my courage in both hands to shout "break your neck" [...] For me I cannot, alas, given my age, pretend to go to the school of the classics, but having gone back in time, I am now painting snails, the ones I used to draw as a child on the ground [...]....] And also snakes [...] [my] letter which contains a magic formula for the cure of drunkards [...] It seems to me as legitimate to paint a mile of snails as it is to paint a mile of portraits". The painter Pierre Giraud was the brother of Robert Giraud, a friend of Chaissac and Doisneau. Robert and Pierre were close to Jean Dubuffet when he founded the foyer of Art Brut.
