Anything from a band or artist that split up or died before you were born
I’m often quietly amused when I see teens wearing Led Zeppelin US Tour tees, as well as Ramones tees.
Never did see the Ramones, sadly, and the Zeppelin tee I had from Earle’s Court was an iron-on design, and faded after six months.
Wouldn’t fit me now, anyway, and my Buzzcocks tee is too tight to wear in polite company.
I’ve got three Curve tees from two different tours back in the 90’s that are still wearable, mind.
