I just acquired the incredibly rare 76 oz jug/pitcher with ice lip, in the Diane etch, which was made by Cambridge Glass from 1932 – 1949. Outside of minimal wear on the base, it is in “pristine” condition. From what I can find on the internet, no one even has a photograph of one posted (there are pics of catalog pages). Any help in determining it’s value would be greatly appreciated. Thank you, Helena
