Rare work from the beginning of the surrealist movement (1925-1940). Original collotype using the rubbing technique invented by Max Ernst, who called his process "frottage" (French for "rubbing") and claimed it as a form of Surrealist automatism. Ernst created these images by placing paper atop various materials and rubbing the surface with a pencil or crayon. Inspired by the resulting textures, he added details to transform them into fantastical landscapes, objects and creatures. Reference: MOMA Collection, NY.
