Just had lunch with Joe. He told me a story about Robert Irwin.
Irwin was Joe's instructor at Chouinard Art Institute in the early 1960's. Joe was working three jobs to stay alive and pay for art school.
At the end of the semester Irwin told Joe, "get out of here, you don't need this, you're ready to be an artist."
Joe got out of there. He's been making art ever since.
