In this bonus episode, Platemark host Ann Shafer coaxed co-host Tru Ludwig into talking about being an artist and art historian, and how being a professor in both disciplines plays out. It's a fascinating confluence of ideas and passions in one person.  Fun fact: Käthe Kollwitz is Tru's patronus. Another fun fact, Käthe is pronounced Kay-tuh. Tru's website: thepurplecrayonpress.com.
