A major New York art collector is poised to donate his trove of some 2,500 pieces of contemporary drawing to the city’s Museum of Modern Art. Harvey S. Shipley Miller, who until recently collected mainly Russian avant-garde books, has served on the MoMA board since 2001, and spent only a year amassing his impressive collection of drawings, which is insured for $75 million. “The collection’s focus is on artists who have emerged in the last two decades, but there are also contemporary works by artists who became prominent in the 1960’s and 70’s.”
