Its title was: The phantom of (wich?) opera. It was a comic without dialogue and a twist of the classic The phantom of the opera. The twist was that the humans where exchanged with all kinds of bisarre, alien creatures. Christine fore example was a green-skinned, faceless being. I dont remember the magazines title but i am rather sure it was in the 90thies i saw it. If anyone can help me find it i will be grateful.
