Pablo Picasso's endless fascination with his lover's character and form led to radical shifts in his conception of portraiture and the mystical metamorphoses that the act of creation entails. Picasso's secretive love affair with Marie-Therese Walter, which began in 1927, inspired a radical shift in his conception of portraiture. The exhibition and catalogue present Marie-Therese as a primary vehicle for his experimentation during the period, including several works never before seen in the United States as well as previously unpublished personal letters and photographs.  Picasso and Marie-Therese sheds new light on the interpretation of one of the most creative relationships in Picasso's rich and varied oeuvre.
