Whilst reading the May number of the English House and Garden magazine I discovered in one of the redactional articles a beautiful  stylised vase in pottery made by Sylvac. It was listed by www.collectionsof.com  for whom I have already set up a link.

Actually there is a second one, but smaller, included in the price of the one, mentioned in H&G.

SylvaC Nautilus Shell.

I like the site for the diversity of their collections.
