Thanks very much. There is another portrait of him slightly older in the curtains, but it isn't showing up yet. As the painting dries, it thins, and I find that the marker underneath comes through more strongly. Thanks!
I don't think you can see the one in the curtains... I really doubt it. It's barely able to be seen even in person. As the oil dries, it will become more apparent. The ones in the forehead are able to be seen a lot.
