Garrison Boscobel will present noted Currier & Ives collector, John Zak, at 2 p.m. on Sunday, Aug. 29. Zak will give an illustrated lecture on the history of Currier & Ives, followed by a visit to the gallery for further discussion and questions regarding the current exhibit, Currier & Ives on the Hudson. Zak is recognized as one of the pre-eminent collectors of Currier & Ives in the country. He has been collecting the firm’s lithographs since the late 1970s and in 2007 served as a consultant to a PBS television program about Currier & Ives produced by WGBY in Springfield, Mass. He is currently the president of the American Historical Print Collectors Society and lives on Long Island. Boscobel’s major summer exhibition, Currier & Ives on the Hudson, features prints of the 19th-century publishing firm that issued thousands of lithographs on a wide variety of popular subjects, earning their reputation as “printmakers to the American people.” Boscobel’s exhibit of 35 hand-colored lithographs focuses on Currier & Ives landscapes and views of the Hudson River Valley, as well as depictions of river activity, such as steamships and ice boat racing. The exhibit also examines the process of lithography and features the display of a 150-pound lithographer’s stone. The lecture will take place in the Thompson Room at the Carriage House. Boscobel is located on scenic Route 9D in Garrison. For more information call 265-3638, ext. 115 or visit www.Boscobel.org.
