Vintage Gulf Coast Winter Classics T-Shirt

Vintage T-shirt from the Gulf Coast Winter Classic horse show in Mississippi. Tag says XL, but I think the shirt has shrunk over the years. It’s probably more like a youth large or adult small. Unisex sizing. I believe the shirt was originally a light green, but has been sun bleached from wear. Also has one tiny stain and a name on the tag has been crossed out (see photos).
