Manhunter (1988-) #4
OK, hang on, I’ve got a bone to pick with that closing shot of the masks on the wall: I spot Green Lantern’s domino mask and Doctor Fate’s helmet. But Green Lantern’s mask is generated by his ring. If it’s genuine, it would disappear the moment his ring runs out of power. Probably earlier, if he just stops willing it to exist. And there’s only one Helm of Nabu.
