YoyoFactory did this thing where they made the Protostar, PGM, etc. and called it their “Death to Metal” line. So I would imagine that the shirt comes from YYF in some way shape or form.
That was awhile ago, I am not sure if YYF still has designs for this particular line of throws. IF so, you might be in luck, if not then you will probably have to ebay it or something. Shoot Ben an email, worst he can say is, “STFU GO DIE!” right?
so hopefully I am at least moderately accurate on what I have posted here and -hopefully- it helps you find the answers you need Happy New Year!
