Lovely find, Michael! Iīd be greenest green if I hadnīt both of them already ...
Especially the 3d-effect of this decor is quite stunning, innit?
Unfortunately I donīt have the Wiedmann exhibition catalogue mentioned - itīs
on my wishlist for years now, but there doesnīt seem to be any copy available.
This decor however is quite close to the Fumaris range apart from the fact that
these additionally have a silver-nitrate decor to the outer surface.
Iīd say there is a very high likeliness this also is a Wiedmann decor.
