This mug I believe was a promotional gift from the Hamburg – Amerika Linie. Norddeutscher Lloyd is just one of the names on bottom of large mug. Overall size is 5 ¼” tall, bottom of piece measures 4” in diameter with top at 3 ¼”. Nice piece with map of Bremen picking out all the towers of the city. There is some crazing to this piece but no chips or cracks.
