Pablo Picasso's endless fascination with his lover's character and form <br>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experimentation during the period, including several works never before seen in the United States as well as previously unpublished personal letters and photographs.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.
