Author Harold Holzer examines Civil War artifacts featured in his book, "The Civil War in 50 Objects,” drawn from the New-York Historical Society’s collection. He’s joined by Columbia University history professor Eric Foner -- who wrote the introduction for the book -- in a discussion on the collection’s history and themes. Objects include Confederate flags, Grant’s handwritten terms of surrender at Appomattox, and framed leaves from Abraham Lincoln's funeral bier. The New-York Historical Society hosted this event. It’s just under an hour.
