A rich ceramics collection is present in the Bowes Museum, in the village Barnard Castle, Teesdale, U.K.. One of the objects is this piece of Wallendorf porcelain, made in ca. 1785 . The bowl and cover are illustrated with animal figures and some plants.
On top of the cover is a large snail, which is rather stylised, especially the shell and the head of the animal. However, a detail what I wouldn’t have expected is the lighter coloured rim of the foot. The species is unidentifiable, but the shell is dextral.
