Hi
Does anyone know this mark\pp\/
\thanks

Possibly Diana Peyton based on the example in the book but I dont have a verified example of her mark

It looks like a Diana Peyton mark that changed over the years but all of her work that I have seen is either celadon or white glazed and so the glaze gives me a doubt.

Here are a couple from know pots of hers: -



The last one that is difficult to see, as it it under celadon glaze on porcelain, is most like the one on this vase.

Diana used to organise a small crafts fair in a church hall on the west side of Hyde Park once a year where the vases with these marks were bought by Trevor Coldrey, who started the Harlequin Gallery in 1990.
