I still got my Phoenix festival shirt...I'll go dig it out to find out the year and to take a pic.
It's a grey short sleeved tee with the 'Poppies character' looking off his face. On the back there's a can squashed in a bit at the sides with "Poppies In-fest 94". I think!
Damned cool shirt tho! It's got a rip in it from the very night PWEI played there from where I tried to unscrew a bottle cap that wasn't the screw-off type, duh. I was extremely battered at the time tho.
