I have been offered this stein, but would seek some advice please. It was purchased post WW2 but a member of the occupation forces. There is no lithopane in the base, which worries me, although it all looks suitably 'old'. Artwork is said to be painted and the lid bears a cannon, with a rampant Bavarian lion on the handle. Dedicated to Emil Popper 1901-1903, which is I assume his period of service. Asking price $100. Is this a good one, and is the price fair please?
