If I could just stop laughing, I think I could take Colin Berry seriously when he asks, “Does the Man on the Turin Shroud really have a beard and moustache? (Or is the image an ‘impactogram’?).”
It compelled me to wonder if there were other possibilities. Perhaps shaving cream. Was a part of the preparations in the tomb a shave but while doing so they ran out of time. In other words, in situ shaving cream. Certainly the top panel of the Hungarian Pray Manuscript illustration shows that this was what was going on. Or maybe it was a combination of shaving cream and impactography as seen below on the left.
Note: The top picture was cropped from one suggested by Colin that appears on dozens of websites. The one to the left only appears on five websites.
