The narrow strip of additional canvas along the top edge can be seen clearly in the x-ray image in the centre. There is cusping along the top and right-hand edge, which suggests that the support was cut from a larger, pre-stretched, canvas. The brushwork technique in the fleshpaint is very clear, with thicker passages of finely blended paint used for modelling. There are some damages and paint losses in the costume and collar, and the restoration in these areas can be seen in the infrared reflectogram on the right. No underdrawing is visible using infrared reflectography.
