This plaque bears angel kneeling left, playing a violin. Signed at lower left with (TSS monogram).
Spicer-Simson's Angel with Violin is an early work that he created while staying in Paris. It is very much an Art Nouveau motif and demonstrates how strongly he was influenced by the French masters that he worked with.
The plaque is a little gem and supposedly very rare. It is very different from most of his other medallic works that were predominantly portraits. There is a companion piece depicting an angel playing the lyre called "L'ange au Lyre" that might be even rarer, at least it has not come up often in auctions.
The rectangular plaque measures 48mm x 52mm and was struck in Paris.
