By far Frank Zappa's most popular choice for album art, Cal Shenkel was a hero of mine from the time I was in high school.
One of my true heroes, Zappa wasn't especially kind when I interviewed him. I honestly was not great at it. He insisted I got into radio to get laid, and actually it was because even as often the best qualified journalism graduate, the news stations were obligated to not hire white men. I simply did not know what else to do. When you meet your heroes, you're often let down. This did little to diminish my admiration and enthusuasm.
