This is very interesting, and I think unusual. I would like to compare this or similar 12 oz Pepsi WB LOS glass to a "regular" 12 oz think WB or other Pepsi glass and see what the differences are. I don't think the CCC mark is usually seen on these, but am not sure, don't have some to check but will try to find a couple in collection and see what they look like.

I am not sure what "NOS glasses" refers to though.

very cool ,Mike - always something new and interesting with glass collecting! thanks.
