Metallica did reprint some of their 80s tees in the 90s under their own tag. And there are a lot of modern day prints of that shirt (that don't have the Metallica tag.) But I believe that's from the 90s - here's a similar one from IVWT.
(Please note: Legit checks I do in this forum should not be considered 100% conclusive; I'm simply giving a gut reaction based on the limited information provided.)
So which mean my t shirt is totally vintage 90's right?
Because as i in second link the new metallica t shirt,it don't have a copyright of pushead at the front.
