Merch question

Is this a reference ? I’ve seen that they had a concert with the angel of water in the background but that was the only think I found about it. Is it rare/ old merch ? I found it on depop for $20 or a bit more and I was wondering if it was worth it because I’m broke and if I want to buy merch I won’t want "fake merch" (even if the tag says my chemical romance idk if it’s clear)
