Original small (about the size of a coffee mug) 0,25L bier krug with DRP markings! The graphics are for Hackerbräu München Nährbier which is advertised here as a nourishing, healthy beer with a low alcohol content. It is in decent condition with wear, discoloration, imperfections and some dirt. Needs a good cleaning.
This is a krug, not a stein. Stein is what English speakers and tourists say. In German a stein is a stone, and is not used to describe a beverage container.
