Wonderful Green Cup - but difficult mark

Hallo all.
This cup has the most extraordinary green glaze...very attractive.
There is what I think to be a small mark on the base rim. This may include a D and/or a W...or neither.
I should be grateful if anybody recognises the style or the mark. Thank you.

Whilst I am hear, despite the dystopian times in which we appear to be heading, I should like to wish all readers a healthy, smiley Christmas.

Of course I meant HERE and not HEAR!!

That colour makes me think of Farnham.

Makes me think of Vallauris or Spain

I know that they are modern European and thought someone else would remember, as I think they might have been identified before. Alternatively, I might have seen a whole set in the south of France.

Belgian?

Jacques Blin is a French potter who has used a similar coloured glaze.
