Two marks of Lippa family in Vienna.
L&C stands for Lippa & Company.
GL stands for Georg Lippa.
Both marks are found alongside Diana mark, either 900 or 800 standard.
Vienna Secession silver (Jugendstil, Art Nouveau) (e.g.for Wiener Werkstätte), but also traditional design with hand painted enamel.
Any info about Lippa silversmiths is appreciated.
Thank you.
