Pottery Chatroom Board

Thanks for the site Shelly, I had found that one with the number 29 looking like mine but couldn't get any further with it. I don't know if they are Fs, 7s, or what either! Might be a signature too. My mother claims it's really old and worth a lot ( but she claims that about everything that was passed down to her). She's in her 90s and is doing well but doesn't remember anything else about the bowl.
