Boris Wilnitsky has these notes about the portrait: "Portrait of Countess Ernestine Palffy Hoyos (1764-1843), wife of Count Karoly Palffy (1767-1823) and daughter of Johann Leopold Innocenz Count Hoyos-Sprinzenstein and Maria Leopoldine Countesse Herbenstein.This portrait came from the Viennese heirs of the Family Palffy. It has been in the collection of their family castle for two hundreds years and was entitled later with the name of the sitter in white color following the custom back then of naming the sitters of paintings in the gallery of ancestors. This inscription was rather coarse and disharmonious for the composition, so that our restorer removed it. The photograph of the painting before restoration can be seen in our additional image.
This painting matches absolutely all stylistic criteria of the works of the Austrian artist Johann Baptist Lampi the Younger (1775 Trient - 1837 Vienna)."
