[Mccoypottery-talk] mark

[ELIZABETH VAUGHN]

Lois Lehner's book on marks shows MP as one of the Morton Pottery marks,
but she shows it with a dash and a number after the MP, and also USA.
After looking through the whole M section, that is my best guess. I have
books on Morton if you want to send me a photo at revaughn@webtv.net
