There is no tag, definitely has the smell and it is way longer than it is wide. Is this 70s? There is single stitching as shown on sleeves.

Hello, i know this isn’t the typical shirt posted here but I’m looking to see if anyone can possibly put a decade/age range on this shirt i found

I didn’t want to resell. I just wanted to make sure it was from the 1970s because i have an obsession with the decade. It’s more of a personal thing why i was making sure.

I’m wondering if this shirt is true vintage. I’ve placed pics of the tag and the iron on used.
