If you're going to serve a fancy beer you have to use a fancy glass! Like many brewers at the time, Lemp reinforced the brand name recognition within the marketplace with glasses (usually given away to restaurants, hotels, taverns, etc.) bearing the Lemp name and logo.
Prior to the manufacture of paper cups, shell glasses were produced as throw-away drinkware. Their thin construction and and small size made practically impossible to wash without damaging the glass. Consequently they were typically used once by a customer and thrown away.
Three variations of Lemp 'Gemutlichkeit' shell glasses; 4-1/2", 4-1/8", and 3-3/4" heights; circa 1900.
