GUEST: When I first started dating my fiancée, I started speaking to her mom and her mom was a great historian. She knew I was interested in history. They had this collection of postcards in an attic, and she dropped them in my lap, and I've been going through them for the last three years trying to make some sense out of them.
APPRAISER: These are from the House of David, which was a commune established in Benton Harbor, Michigan, in 1907. They were an unusual group. They were banned from shaving, cutting their hair, having sex, or eating meat.
GUEST: Really?
APPRAISER: But they also had a hell of a baseball team. They would barnstorm all around the Midwest in the '20s and '30s, playing and beating most of the local teams. There are very avid collectors of House of David objects, especially those showing the team. In a retail setting, I think you're probably looking at $100 each...
GUEST: Really?
APPRAISER: ...for these photographs, yeah. They're amazing.
GUEST: Yeah, baby!
