Vintage Denver Broncos super bowl Raglan T-shirt

Vintage raglan! Has a stain on the left arm, I assume this is very removable. Haven’t messed with a restore yet, but if you are interested I could always give it some TLC! Please let me know!! Also please let me know if you need measurements as this item is NOT A TRUE MEDIUM. Item has shrunk to more of a S, but again please ask for measurements if you are unsure if this will fit
