The shirt is really cool. I'm a big fan of knock off shirts as well. Here is a picture of the shirt I made for my all-ages music venue.
(These are some kids that regular the venue.)
Nice! I know some people hate all-ages venues but that saved me. I went to my first show at 12 and was a regular by like 14, so I hated nothing more than 18+ venues. Even at that I missed the best years of punk and hardcore.
