Hi there:
This does have a stamp on the bottom and I did find that this mark first started to be used in 1950....so not sure if that is the date of mine of not ?? I am not sure about everything the bottom means. I mean I have here of KPM -- but still not sure of the date, design of this item.
This Ceramic has that texture some Glass has --- with that *Bark* look
Any more info would be greatly appreciated.
