Dana: What are your favorite art pieces? Mark: One of my favorites is the Mario Wagner piece in the dining room. That one has a pretty cool story. It was a surprise birthday gift from Patti three or four years ago. We saw it in a gallery in L.A., and that was the first time I had seen his work. The gallerist delivered it in person and took me by surprise, and we all ended up becoming really good friends. I like the collage and the 1960s feeling of it.
