Signed Vintage Hand-Painted Russian Brooch of St. George and the Dragon

Beautifully detailed Russian icon brooch appears to feature Saint George on horseback about to slay the 3-headed dragon. Vibrant colors and intricate design. Signed by the artist. Perfect for collectors. This was on display at The Dragon Dreams Museum in Chattanooga, TN. Closed permanently in 2016, I have recently purchased the contents.
