Annie, that was an awesome find! Now if you get that in a T-Shirt, you won't even be allowed to enter the airport!
It was from an art exhibit called Three Apples that celebrated Hello Kitty's 35th anniversary last November in Culver City California. They are selling prints of the remaining artwork at Japan LA. It would make a cute tshirt! That exhibit was so much fun! My bro just came back from Californai, and said he was patted down by random by airport security. I told him to wear a GNR shirt on his return flight, but he refused.
He's not really a fan.
