Antique Art Nouveau William Kerr Sterling Green Man Gargoyle Brooch Fob Pendant

  
Gorgeous and absolutely rare art nouveau piece. A green man/gargoyle brooch pin- watch/fob pendant holder. It is unsigned for metal purity and unsigned for makers mark but I found the same one on a website with curated pieces by William Kerr. It tests positive for sterling silver with the acid test. It looks like it might have had a gold wash at the beginning which most of it wore off.
