The large repaired damage at the lower-left corner is very obvious in the x-ray image in the centre and there are repaired holes at the top, which are probably nail holes from a past hanging method. The x-ray also shows that the eyebrows were painted first, and the fleshpaint was then painted up to the edge of the eyebrow. The broad brushwork of the priming layer can be seen clearly in both the x-ray and the infrared reflectogram on the right. Underdrawing marks out the features with confidently applied lines and definite shapes.
