“Dennis the Menace” takes over “Blockhead”! The wonderful Marcus Hamilton, daily cartoonist of “Dennis the Menace”, is here to talk about Dennis, the Mitchells, Mr. & Mrs. Wilson, his career as a top-notch illustrator in the 1970s and how a  chance glimpse of a TV interview with Hank Ketcham revitalized his career and led him to a dream job drawing one of the most iconic characters in comics history.
