This is a t-shirt design I did in 2007 for our company division’s drinking team here in Japan. Unfortunately, we decided the cost of printing the t-shirts wasn’t worth it. Maybe I should submit it to threadless?
Update: This is now available on Redbubble as a T-shirt, hoodie, sticker, or print!
It is also available on society6 as a print, T-shirt, and iPhone case.
