Auction introduction: Christie’s is pleased to offer Exceptional Impressions: The Alan and Marianne Schwartz Collection on 23 October in New York. One of the largest collections of graphic art in the United States assembled over many decades, the collection spans the best of European Old Master prints, German Expressionism and American Modernism. Highlights from the collection include Picasso’s La Femme qui pleure I (Weeping Woman I), Rembrandt’s etching The Three Crosses, Erich Heckel’s Fränzi liegend and Edvard Munch’s Angst. The collection also includes one of the most significant groupings of early 20th-century American prints to come to market, including important prints by Edward Hopper, Charles Sheeler, Benton Murdoch Spruance, and many others. Alan and Marianne Schwartz were champions of the print collecting community. Their collection was exhibited at many major institutions during their lifetime, most significantly in the landmark exhibition Master Prints of Five Centuries at the Detroit Institute of Arts in 1990.
