Lot Essay
Powolny trained as a sculptor and ceramic artist at the Fachschule für Tonindustrie in Znaim and at the Kunstgewerbeschule in Vienna where he taught from 1909. He made several designs for engraved glass for J. & L. Lobmeyr between about 1914 and 1925 including a series of tumblers similar to the present lot. See Judy Rudoe, Decorative Arts 1850-1950, pl. 106 (cat. 244) for another tumbler from this series in the British Museum and for a goblet with similar roundels shown at the Paris Exhibition, 1925, see Catalogue, 'Exposition International des Arts Décoratifs et Industriels Modernes, 1925' vol. V, pl. LXXXVIII
