What I would really like to find but never have are sketches or paintings of him. I imagine the Romans may have removed them ala Muzzie style to remove them from the public. If anyone knows where these might be, I would love to see them if they were done while he was alive...
Try the Shroud of Turin. I recall reading something about the research done years ago. The piece used in radiocarbon dating had apparently been a patch put on after the fire singed the Shroud, so it did not ‘read’ old enough to have been from.the time of Jesus. The Roman Catholic church will not allow another sample to be taken from the Shroud.
As a non-Roman Catholic, I don’t put much stock in ‘relics’, but what I’ve read of the Shroud, it sounds like it well could have been Jesus’ shroud. Apparently, a ‘negative’ of the Shroud will give you something close to what you desire.
