Quoting Alex Mac
Dang...I have all the parts, I'm sure of it, and I can find every one, BUT the shirt! I'm positive that I have bought several sets with that shirt in it though, so I'll keep looking!
ironic... the shirt is kinda rare. if you have my old sigfig, just swap heads. also, if you happen to make a bricklink purchase, and the shirt is in the store, just buy a new one. hope this helped
