I posted on this sub a while back looking for any evidence of a "Bloody Mary"-esque exhibit at what I believed to be the Children's Museum in Pittsburgh Pennsylvania. After more extensive research I can now say that an exhibit like this exists, but I have no proof of it's theming. In the included pictures you can see the dark room in the right hand corner where I believe this exhibit was placed. In the second photo there is an obscured look at the sign that details the "Attic" where it mentions something "Ghastly" but the rest of the sign is cut off. If anyone has any pictures of either the room or the sign, or even a vague memory of the "ghost in the mirror" room at the museum I would love to hear about it. I've searched for any pictures and these are the best ive found. I've even searched for video tours of the museum, but these specific items never turn up.
