Joan Rivers' treasure trove
Comedian Joan Rivers may not have had everything she wanted, but whatever she had, she kept. Tucked away in midtown Manhattan in a nondescript high-rise, her office looks just as it did when she was alive, packed with mementos of a long career - jokes, scrapbooks and photos - as well as every thank-you note, every airline ticket, every scrap of paper dating back to her grade school days. Tracy Smith talks with Joan's daughter, Melissa Rivers, about her mother's paper trail obsession.
