Always meant to ask, who made all the signage/labels in the batcave? I mean, if it was some random sign maker, they pretty much had more intel on whats in there than anyone else, excluding Bruce Wayne.
Honestly I always figured it was Alfred. He more than likely does not make the kind of money he should be, hence why Bruce kind of has to let him live at Wayne Manor. Otherwise he'd either (1) spill the beans on what he knows, or (2) just sue his ass for appropriate compensation.
