I just inherited about a dozen items (plates bowls cups) and from the few I can read say Grahm Mfg. Co Quadruple Plate on the bottom. I’ve googled and cannot find any info about the manufactor. The family theory is they first belonged to my Great Great Grandmother however I really have no way of knowing if its really that old.
So what I’m asking is, has anyone heard of this Graham Mfg Co and if so do you know where I can get more info?
