Thanks, Kayelle, for the link. I'm going to have fun surfing through all the information.
I was quite lucky to get the baker but we live in a very, very rural area and I honestly think folks didn't know what it was. The staff at Goodwill apparently didn't either because of the low price. They price crappy skillets much higher. I could believe that, since it was made of terra cotta, it might have something to do with planting/gardening. Especially with the scroll-like embossing on the top. No matter. It's mine now.
I was just at the right place at the right time.
