From the Shirtpunch.com's interview with the artist:
"Question: What inspired this design?
Answer: Driving from New York to Colorado in a 26-foot moving truck, twelve hours a day for four days can make you a little punchy. I thought this shirt up en route, many hours in, and it became my first commercial tee design."
About Shirtpunch.com: It's simple; ShirtPunch is your home for limited edition, pop culture tees... but there's a twist! We only offer one shirt every 24-hours, and they're always only $10.
