I have a set of 6 glasses that I belive to be from the 1950's. They have a pattern of a blue and black roosters (very stylized) on them. The glass curves in at the bottom and is thick on the bottom too, a differnt shape then what I've seen on ebay. Anyways they have the signature of Dyball on them. I can find any info on this maker. If anyone has any info that would be great.
Thank you for your help!
