Vintage T-Shirt Forum & Community Authentication Appraisals

Curious of authenticity. I haven’t seen a tag say lg instead of large. Am I wrong? Just would appreciate your eyes on it. Also, curious of potential value. thanks for all the help as always

I'd need to see a better shot of the tag, but gut says it's fine, too compliated to fake, not enough $$ to do so. Probably a $100-150 piece.
