Shirt help!

Hi guys. I’m a football shirt collector, and have acquired this Forest top. It looks like the 3rd shirt from around 1999-2001, that I understand was released but never match worn (which may explain why I can find very little of of online), however the colour is black and not the purple type colour I’ve seen elsewhere.

Does anytime know the story of this shirt? It feels legit and like it’s from that era, however bar one eBay listing from the USA I can find next to nothing about it, so it’s truly stumped me as to its story & whether it’s real!

Any help greatly appreciated 👍
