This monotype was produced by the process of erwinographie, a technique based on the use of a light-sensitive gelatin ground onto which a drawing is exposed. The gelatin is then heated to create a hardened surface from which impressions can be pulled and individually coloured. In her note on the technique, Brigitte Baer describes how on 26 May 1932 Picasso experimented with erwinographie, hand-painting the few impressions with greasy printing ink or watercolour thickened with gum arabic. Each impression taken is unique and presents many characteristics of an original painting with the hand-applied gouache ground.
