At the Non-Motivational Speaker Series, New Yorker cartoonist Farley Katz reveals the secrets of the secret society known as the Mustache Club.

The Non-Motivational Speaker Series is a free monthly event held at JLA Studios in Brooklyn. ILLUSTRATION was June's theme. Speakers included artist Molly Crabapple, creator of Dr. Sketchy's Anti-Art School, a cabaret-life-drawing class with 57 branches around the world; New Yorker cartoonist and editor of the magazine's comedy blog Farley Katz; and Josh Neufeld, author of graphic novels A Few Perfect Hours and the acclaimed A.D.: New Orleans After the Deluge, to be published by Pantheon this fall.
