[Bach, Johann Sebastian. (1685-1750)] Carved Bust PortraitA rare and finely carved bust portrait of the great composer, ca. 1850s, likely based on an early nineteenth century engraving. Carved walnut with good color and patination. Light mounting remnants on the verso. 4. 75 x 6. 5 inches (12. 2 x 16. 5 cm). Secular portrait carvings from this era are uncommon. The only verifiably authentic portrait of Bach was painted in 1748 by Elias Gottlob Haussmann and shows the composer in a white shirt and blue coat
