Original color colotype, crayon and lithograph by Pablo Picasso (Spanish 1881-1973) “Profile of a Lady”, Signed and inscribed "Bon a Tierre". A unique experimental trial proof illustration for a gallery catalog of the artist’s works. The text would have been printed on the blank space to the right. Picasso has experimented with additional yellow, green, and red lithographic ink. No edition seems to have been published making this a unique working proof.
