In celebration of the physical release of New Super Luigi U on August 25th, Nintendo held an event in Chicago on August 12th where one of the trains had been designed with New Super Luigi U imagery on the inside and outside. In a tweet released by Nintendo of America's official twitter account, this picture was posted along with the following message:
"Mama mia, the Chicago buildings are tall! Now I know how Mario must feel. (It's funny because he's shorter than me.) pic.twitter.com/8TXMIal7FW"
