This beaker represents the tradition of Bohemian and Viennese decorative glassware that flourished during the 19th and early 20th centuries. Anton Kothgasser (1769-1851) was a renowned Austrian glass painter who pioneered the technique of painting transparent enamels on glass, often depicting architectural landmarks and cityscapes of Vienna. His style was widely imitated by Bohemian glass makers throughout the 1800s and into the early 1900s, creating a lasting legacy of amber-flashed and gilt-decorated beakers.
