This catalogue is intended to enable the reader to survey Picasso's development and the great variety of his artistic production from 1894 to 1955. Each of Picasso's periods is illustrated by separate groups of pictures. For the sake of completeness we have also included some sculptures. Certain special groups make it possible to inform oneself separately about special subjects and techniques such as sculpture, ceramics, or the image of man in Picasso's works. The chronological order of all works and periods has been retained as far as possible. The measurements indicate height and width insofar as it is possible to ascertain them. As for the technique, the medium, the location, or the owner of the works reproduced, see "List of Works Reproduced", page 487.
