Vintage T-Shirt Forum & Community Authentication Appraisals

Got this out of my uncle's closet along with some crazy fantasy/wizards shirts, and all his union/sports/drinking shirts.
Only tag that remains does not have a brand, but it does state Made In Canada, which is where we live.
Thoughts on authenticity? I can't find reliable comps with this imagery and no text on the base.
Tag states Size L, Measures just under 26" in length and 19.5" pit to pit.

Looks like a beauty, eh?

I'm in Canada too so I can say that.

Are you in Toronto? This looks like something that was purchased at a headshop on Yonge street.

It's legit vintage, but it's a bootleg, made in the era.

We're in the outskirts of Toronto but that definitely goes with what my gut was saying for it. Matches with some other headshop shirts he had as well. Thanks for the input!
