stein with linear decoration

You can see a photo of an reproduction of that stein in the collection from Lupo der Wolf. The stein was produced by Merkelbach Manufactur and had a base mark: Modell 2520, designer A. Hanke, 1910. An other stein with that decor (in an other form), model nr. H 2519 you can see in the book Braun geflammt...., side 263. The letter H is the sign for A. Hanke.
