ACCEPT Balls To the Wall 1984 Tour Single Stitch Double Sided T-Shirt Size Large.   The sleeves were cut off.  Refer to measurements for current fit which probably is more like a Medium.

💯Authentic!!  I am the original owner of the shirt purchased in 1984 directly from the band's merch booth.

There is a tiny hole near the bottom on the back side along with some slight discoloration also on the back (See 7th & 8th photos).
