The finish on this late eighteenth century German china cabinet has been entirely restored to its original patina. The piece had been painted top to bottom with an oil-based paint in the 1960s, covering the original finish. To restore the beauty of the piece and increase its value, the oil-based paint was carefully removed to ensure that the original wood finish and 24-karat-gold-leaf applied to the pewter accents were preserved.
