Mark that has a "P" at the bottom????

I have a ringed bowl that appears Bauer like with small rings. It is yellow, a large mixing bowl and heavy and has a crackle finish. I think it is from the USA but not sure. The mark looks like a stamp or picture of a short urn and at the bottom there is a capital P. The tail of the P intersects the bottom of the urn at a 90 degree angle. Please help me, this is driving me nuts :). Thank you so much.
