XL? Well, that's the size my nightshirts tend to be... could get my dad to buy it for me...but nah, I wanna sweet talk him into buying me a Tom Petty and the Heartbreakers Zippo (this is true). Anyway, I could always make my own shirt (and in a size I could wear in public, too...)
As to whether that's an official product or something they just made, I can't tell and it doesn't really make a difference to me. If they did make it, however, they did use official art - even the font "Don't Panic" is in is canonical.
whee Ebay is fun. Once I saw a pillowcase someone had made - well, they took a pillowcase and transferred a drawing they had done of Tom Petty onto it. Very nice.
3nodding Gee, wonder what sort of music I could listen to?
whee But people, go ahead and go for it!
