The New-York Historical Society has announced that a rare copy of the “Stone” facsimile of the Declaration of Independence —one of approximately fifty in existence—will be added to the displays in the Judith and Howard Berkowitz Sculpture Court beginning July 3 in honor of Independence Day. The document is being lent to New-York Historical through the courtesy of collector David Rubenstein, managing director of The Carlyle Group, and will remain on view through July 15.
