Picasso once said that all children are artists, and graphic designer Rob Kimmel of the recent hit blog WanderMonster is out to prove it. Everyday he slips a half-drawn illustration on a Post-It note into his son Ben’s lunch. Ben, who is currently in the second grade, finishes the drawing and Kimmel posts the finished works to the Lunch Post series, which was recently linked to by Wired and EW.com.

The ritual started as a way to stimulate Ben’s growing brain, but swiftly became a fun venture for both father and son. “[The project] started when he was learning how to read and do basic math,” Kimmel says. “It was a game where I would write a simple word that he could sound out, skip a letter and have him fill it out. As he got more sophisticated, they did too. Now he’s basically an equal partner. But that might be giving myself too much credit. Maybe he’s eclipsed me completely.”

The lunch posts started independently of WanderMonster, which was conceived as a travel blog. When he started the drawings, Ben’s school art teacher in Park Slope offered up the window at the front of the building to display them, and that’s when Kimmel started to see it as a legitimate body of work.

“We do things like this all the time,” Kimmel says. “Ben draws constantly. He’s also always building things. His main thing is that he makes up movies and series and movie posters. It’s never like a single movie, it’s a whole line of sequels and prequels. Right now he’s making comic books. He calls them graphic novels, but it’s not quite that grandiose yet.”

Ben was in school and thus unavailable for comment, but Kimmel relayed a story about the bright youngster: “A long-time client and friend of mine, who is Japanese, was very curious to hear what Ben would say about what it means to be an American,” Kimmel says. “Ben looked confused, paused and said, ‘I’m from Brooklyn.’” Spoken like a true budding New York artist.
