This is a 1L beer stein, also known as a Masskrug, from Munich, Germany. It is the official 1998 Oktoberfest beer mug from the renowned Munich Oktoberfest, and it is signed. Vintage Munich 1998 Official Oktoberfest Beer Mug (Jahreskrug des Oktoberfests Muenchen) ① Motif: "Flotte Kellnerin" (My translation: "Lively Waitress") ② Designer: Borena Jankowska ③ Height: Approximately 19cm, Width: Approximately 11cm ④ Manufacturer: Rastal ⑤ Without a lid I've heard that this large stein size, called a Mass, came into use in Munich's popular beer halls because it allowed the establishment to serve refills more quickly, and for customers, it was a better value than paying for 0.5L servings. Furthermore, ceramic steins are considered to retain coldness better than glass ones. This is a beer mug from the Munich Oktoberfest, held from September 19th to October 4th, 1998. Please refer to the photos. Thank you.
