Topic: Glass Tupperware Covered Bowl?

[conak1]

I found and bought a labeled Tupperware Frosted Green Glass Bowl with lid.  I assume it is a bowl for both the lid/plate section has a base ring and the bowl part with the Tupperware label does too. I called Customer Service at Tupperware and they are clueless without an item # and had no knowledge of any glass Tupperware products.  Google didn't help either.  Anyone out there with some knowledge of this "Tupperware" non-plastic covered container?

I have a friend that wrote the book on Tupperware, unfortunately away at the moment. Bump this up in a month and I can follow up then.
