Head of a Woman, 1961 by Pablo Picasso

Picasso's experiments in making flat sculptures were followed up in the early 1960s with a series of works in on entirely new medium and technique. At first Picasso produced small models using folded paper and cardboard, thus recalling his use of these materials in his early Cubist sculptures. To make the models sturdier, however, Picasso introduced sheet metal. He then pointed the surface of the metal as if it was a canvas, thus producing an amalgam of painting and sculpture. In this example, Picasso has treated line and color as independent. Black lines define the features of the sitter, outlining the hair, eyes, nose, mouth, and the shape of the neck and shoulders. However, these lines fail to contain the non-naturalistic colours that have been randomly applied to model the face. Thus, Picasso adds drawing to his conflation of painting and sculpture.
