Due to restoration, the folds in the costume are more evident in the image taken in ultra violet light on the right. Some restoration in the flesh paint and panel join can also be seen, as well as the change in the height of the chair back. Comparison of the x-ray in the centre and the image taken in ultra violet light shows that very little of the original lead-tin yellow paint remains in the inscription on each side of the sitter's head, although the monogram and the date on the left are in good condition.
