I have a great photo of one of the ballroom ghosts holding "my" glass goblet, thanks to some great detective work from my pal Dale! Here is the original ghost photo, and beside it is an enhanced enlargement of the goblet. And then, beside that, I inserted a new photo of my goblet, trying to imitate the lighting conditions of the ghost photo, and the match is amazing! Thanks Dale!
It's looking like we have a set of haunted mansion banquet goblets! Cool!
