I thought one couldn't even tell that a body was visible on the Shroud of Turin until about 100 years ago....x-ray? .....the two look remarkably alike.....I'm not buying the artist bit. I am going by the two side by side pictures, not the one that looks like it was a Raphael.
The Shroud of Turin has always showed both the frontal and dorsal images of a crucified man, head to head. These images were very hard to see close up... in fact, you couldn't. You had to be standing at least 10 feet away to start seeing the pale images. Blood stains were apparent at both close and far distances.
In 1898, Secondo Pia, an Itallian amateur photographer, took the first photographs of the Shroud and found that his glass plate negative was actually a positive picture... implying that the Shroud itself was a negative! This discovery of the "photographic" nature of the Shroud triggered a wave of scientific investigation that has yet to abate, 108 years later.
The image of a face in the "Veronica's Veil" that is held by the Vatican (the one in the side-by-side picture with the Shroud) is VERY hard to see...
"A present-day liturgic artist, Isabel Piczek from Los Angeles, who saw the Veronica in 1950 while she was working on a fresco for the Papal Biblical Institute, described it to me in the same way, adding resolutely “you couldn’t discern any face or features, not even the smallest sign”."The Vatican has not allowed any scientific examination of the St. Peter's Veil, so it is hard to say. Again, I would like to see much more investigation into that veil. Some VERY good exact size photos need to be taken of the Veil for one to one comparison of any features and bloodstains.

I think that the Moneppello Veil has been pretty much "busted" as a pious mistaken identity. I also think the Vatican one has a better chance of being the "Real" veil... if there is one.
As I said earlier, most Shroud scholars are of the opinion that both the Veronica and Mandylion Traditions are remnants of the way the Shroud was displayed in its early years with only the face showing. Early pictures of both the Veronica and the Mandylion show a face on an oblong horizontal cloth surrounded by a latticework... folding the Shroud four times in two lengthwise results in the face showing. Put that folded cloth into a frame with a lattice you get something that looks like the early pictures of the Veronica and Mandylion.
