I saw someone wearing this not too long ago on a subway here in New York. It was really funny because I couldn't believe what I thought I saw, and the woman who was wearing it promptly put her arms or her bag in front of the shirt as she sat down on the subway seat -- so I had to keep taking peeks at her for many, many stops to see if I could finally get a good look at the shirt! And finally I did.

The one she was wearing was slightly different than the one in the picture, it had the word "recycle" underneath the "SMiLE", too. So it's not really a Beach Boys/Brian Wilson SMiLE shirt, it's a shirt with an ecological message.
