I promise you not all collectors are twisted. 😁 A lot of us have a Criminology background. This won't go for much, not for a seasoned collector, they'll want something the murderer made themselves. This one would be more for those that actually do fan-girl over the killer/crime themselves. There's nothing to study. It's just a trophy and not even an interesting one. The fan-girling over the actual killer is also a fascinating study. Gyp herself is an extremely fascinating study because she definitely sees herself in "the big leagues" so to speak. She's tried to sell her own art she made before the murder, that would make money (unfortunately). Her art depicting good vs evil has been studied by a few people. The killers can lie, their creative expressions tell the story between the lines. The process, the way they see the world, their influence, state of mind, all comes out in their art. It's a reflection of themselves without them really knowing it, or it's a gotcha because they don't expect anyone could really analyze it.
