Valentine Hugo (1887-1968) Portrait Of Picasso

Valentine HUGO (1887-1968) Portrait of Picasso 1936, etching, 30 x 24 cm (plate), 19.5 x 14 cm (copper), titled "Picasso" at the top, signed and dated 14/3/1936 at the bottom right in the plate. Light foxing.
This rare print by Valentine Hugo was intended for Picasso himself in thanks for an engraving received from the Master on March 14, 1936, as attested by a letter from the Picasso Archives of the same day:
"Saturday evening, March 14, 1936 42 rue Fontaine
Dear Picasso, How wonderful this engraving that I see again at this very moment - It is an immense painting - it contains everything that I love and everything that I do not yet know and that I will find there (..) Here it is at my place now".
Valentine Hugo then felt an immense admiration for the artist, which she expressed a week earlier, on March 7, in another letter:
 "Saturday March 7, 1936, Dear Lioness I would like to see you again soon and yet what could I complain about - in not even eight days - you - your poems - you - your wonderful exhibition - you here - and your poems every day for me and at night too - I live with your colors - your shapes - your words - and more than you can believe your thoughts around me - in me - in my head - in my heart and in my body too - how beautiful life is Picasso". This work is today a precious testimony to the intimate bond existing between Valentine Hugo and Picasso at that time.
We also find this same face of Picasso in Valentine Hugo's painting "Portrait of Picasso" (October 1934/October 1948) today at the Centre Georges Pompidou.
Very few proofs of this print seem to have been printed by Valentine Hugo on her press; A similar proof appears in the montage "Autour de Parade" (1916-1965), preserved at the Eugène Boudin Museum, Erik Satie Archives. (photograph attached)
