My folks have a set of 18 glass goblets they received as a gift, probably some time in the late 60s, which would only come out once a year for Thanksgiving dinner. I recently noticed that they resemble the goblets used on the banquet table of at least one of the haunted mansions. I swiped one and took a pic of it. Here is my goblet pic, and a close up shot of the banquet table from the attraction (from Doombuggies.com).
I doubt that anyone could confirm whether my set of glasses are the same as the ones used in mansion, but I thought they looked pretty darned close! If you are a mansion CM, I'd love to hear what you think
