“Since it came into the Museum’s possession, there have been dramatic changes in the painting’s size and appearance. It had been known that portions of the canvas— 13/s inches of the top and 21A inches of the right side - had been folded under since early in the nineteenth century. What is particularly interesting is the confirmation by the Museum’s chief conservator, Hubert von Sonnenburg, that this area (104 square inches) is covered with original paint.”
