Vintage Rolling Stones 1989 Steel Wheels T-shirt - XL?

Purchased around the early 90's when the Stones were on their Steel Wheels Tour. Tag is bleached and faded so can't make out the size but I'm guessing it was an XL since those are the sizes of my other shirts. It probably wears more like a large due to shrinkage. Thin fabric but no rips, tears or holes. Still wearable. I'll answer any questions as best I can. Thanks for looking.
