Identification Pottery Mark

[ceapja]

Hi Everyone, I'm new member to Treasurenet.com. I work in an antique shop and can usually research and identify pieces on my own. I had a piece of pottery come into the shop yesterday and have been unable to identify it. It could very well be a piece made by an individaul interested in making pottery. Just to be sure, I was hoping someone might help me to identify the pottery mark. I have attached a picture of this piece. There is one vertical line and two horizontal lines. The letters appear to be WPBM.




Thank you in advance.

That is a very nicely made piece but clearly the mark is done by hand. Very difficult to ID...

I am trying to put a date on this... I want to say early 20th century, 1920-1950?

I would guess the latter half of the 20th century, 60s-early 70s.
