It's by Winfield, a company in California, and she got it in the late 1940s. I've thought about just using it daily instead of displaying it, but while I don't care if I lose a piece here or there, I do want to take a reasonable amount of care with it.
You could do a web search for the specific pattern to find details. I did a quick search of that company and they made both porcelain china and earthenware pottery. You can also hold it up to the light - earthenware pottery is not translucent. Metallic designs are not microwave safe and are best hand washed (i.e gold trim or accents).
