Period correct (could be from the 1930's-1960's) one liter Löwenbräu Buttenheim beer krug. Marked 1l by the handle. Overall good condition, but it is a little dirty and needs cleaned. Some imperfections in the glaze. Great item for events, much less farby than a modern bottle.
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.
