I've now listed this vase on eBay (230039228562 if anyone's interested) and have had a query from someone about the designer. They say they have a vase which looks identical but is by Nils Landsberg.
Now I'm a bit worried ~ is it possible that the mark on the bottom is an N rather than a P, or can anyone identify it in any other way?
Also, am I wrong in describing it as 'signed' when it only has these marks on the bottom?
Many thanks, John.
