Seven books from George Washington's library at Mount Vernon, each signed by the president, will headline the June 4 sale of “The Library of a Distinguished American Book Collector” at Sotheby’s New York.

Sotheby’s says that it is “the largest group of books from Washington’s library to appear in a single auction since the Bishop John Fletcher Hurst sale in 1904.” Among the offerings is Washington's copy of Jonathan Swift’s The Beauties of Swift.

The 250-lot sale is expected to fetch around $5 million.
