I was definitely trying to find something comparable.
And I can see vintage tees from them but I’m not finding much like your merch from them. So thought this was pretty unique having two other bands on there.
And the cause is pretty cool too

This is the concert poster for the show but again can’t find anything for the merch to it

Looking for what this could be worth.
Definitely has some wear to it. But was looking online and wasn’t finding too many things comparable to it
