Episode No. 613 features author Prudence Peiffer and museum director Timothy Potts.

Peiffer is the author of "The Slip: The New York City Street That Changed American Art Forever." The book, out this week from Harper, is a group biography of seven artists -- Robert Indiana, Ellsworth Kelly, Agnes Martin, James Rosenquist, Delphine Seyrig, Lenore Tawney, and Jack Youngerman -- who worked on Coenties Slip in the 1950s and '60s. Coenties Slip was a street that overlooked the East River in lower Manhattan. Peiffer's book argues for not only the importance of the artists themselves, but for where and how they worked as being important to the development of post-war art in New York. Peiffer is director of content at the Museum of Modern Art, New York.  Amazon and Bookshop offer "The Slip" for $22-36.

Potts discusses the J. Paul Getty Museum's co-acquisition (with the National Portrait Gallery, London) of Joshua Reynolds' Portrait of Mai (ca. 1776). The painting, among Reynolds' finest works, is on view at the National Portrait Gallery. The first presentation at the Getty will be in 2026.
