I actually have this shirt. I bought it at a store in the local mall back in the 1980's,I believe.
I'll search around and see if I can find it online.
No,I was not able to find it online,unfortunately. As I purchased it in the 1980's,its most likely no longer being made.
Although I'm sure there's a print shop that would make a custom shirt off of this image if you really wanted it.
