Here is a video from 1974 that was posted by my cousin and which features his father - my uncle.  Uncle Tom was an artist/raconteur/musician and all-around funny guy who died in 2004.  He was a role model for me as a young artist.   This video shows him as i remember him: charming, eccentric, and unapologetically artistic.  In this video he is teaching at the Minneapolis College of Art & Design and demonstrating his method of silkscreen printmaking.  http://www.tomegerman.com/
