Souvenir

This is a gluehwein mug. One purchases a tasty mug of warming booze and pays a deposit for the mug; of course many mugs are not returned so the stalls are mostly flogging mugs rather than gluehwein . Around the bottom it shows that it's from the Vienna Christkindlmarkt in the Rathausplatz. They are made in Germany and I'd guess that the factory is banging these out all year round for Christmas markets across Germany and Austria.
