Unusual organic art vase/pot - Polperro Pottery

Interesting pot with an simple mark. Looks a little bit like Mark Hanner. Any clues?

Mystery solved. It's FRANK&ANGIE ROBINSON POLPERRO POTTERY . The mark is not very good but it is a P in a box. Here is a similar piece with a slightly clearer mark.

I've included a question mark in the title because yours looks like a red clay body, where as Polperro was usually a grey stoneware. Plus Patricia Fuller has a very similar P mark

Here's a piece from the 70's with a red clay body - I guess that my pot could be early Frank Robinson?
