Vintage T-Shirt Forum & Community Authentication Appraisals

Hello guys !

Purchased this shirt in 2021.
I did not know their would be fake brockum at that time, so I'm now concerned about the fact that my shirt might be a fake.

Here are pictures of my shirt.

Thank you so much in advance, and please let me know if you need more details
Wishing you a great week end !

This is a weird one, the back doesn't have the intense detail the Megadeth logo usually does. But the front appears to be fine as does that tag, so wondering if this is a production error.
