Anyone have places to get some old band shirts?

Many moons ago my mom tossed all my band shirts after I moved out. I have been attempting to rebuild my collection since then but there doesn't seem to be a lot of places that carry the older/"vintage" band shirts. Anyone have some recommendations other than eBay or Etsy?

FWIW, I'm currently trying to find a Metallica, Damage Inc. long sleeve and they seem to be non-existent in XXL.

I've had good luck with Depop, but bigger sizes are super rare. I wear a 2XL also and maybe <5% of stuff out there is that big and even less if it was hot washed to death.
