ebay’s closed auctions would be a start as the ended auctions show the prices each item really sold for, not the made-up fantasies of some listers. Don’t expect too much though, price-wise.

Shown item was made by the [b]Porzellanfabrik Rudolstadt Straus & Söhne AG[/b] between 1895 and 1924. Terms like “Rudolstadt Pottery” and such should be avoided as there was more than one “Rudolstadt Pottery” (in the sense of), next to the fact that such English names were illegal in Germany.
