GBH’s Antiques Roadshow is known for mind-blowing valuations, but often the owners and their stories are the true treasures–like Arnold Shapiro, the guest who was responsible for putting Peanuts cartoons on Hallmark greeting cards. Hear more about Arnold’s 12-year relationship with the iconic Charles Schulz and follow the journey of his comic strip collection from six-figure TV appraisal to a permanent home at the Charles M. Schulz Museum.
