Here's vintage pair of Batman boxer shorts that have never been worn.
I got an auction lot of 1980s unused super hero t-shirts, still in plastic bag packaging and this was the only pair of boxers in the lot.
They're 100% cotton, Made In The USA, size 38 (I guess that's equivalent to Medium size). Within the pattern is written TM DC Comics 1989. They have elastic waist and one snap on the fly. As always, all my offerings may be returned for a refund if you wish (buyer pays shipping unless I have misrepresented).
