Seems like there’s a lot more evidence of its authenticity than this guy’s theory that it’s a fake based on his claim he sees a number 15 on the cloth.
At theory this specific (Giotto) is bound to get disproved unless the evidence for it is overwelming. Too easy for those more knowlegeable than I to kick holes in.

It’s a small tag that reads;
Inspected by #15, Rosie.”
