Someone with whom I’ve corresponded (and I’m very sorry to have lost track of who you are — berate me in e-mail or comments if you ‘cuz I deserve it) pointed out to me once that the casket of glass in which Snow White was temporarily held might make the tube-girl meme older than generally thought.   It seemed like a good thought to me at the time.

Someone else out there evidently thought so as well:
