Vintage ‘91 All Star Blue Jays Tank

‘91 All Star Game in Toronto This feels like 100% cotton, but there is no content tag. Fading around the blue jay print (see photo);also some stitching has come up down around the necklime(see photo). There is the tiniest little yellowish dot also by the neckline which I would guess needs spot treatment. Measurements are approximate : 28” in length (from shoulder seam to back hem; approx 14” drop from shoulder seam to pit; 21.5” pit to pit.
