That's not merch, that's the Veil of Veronica. Very significant catholic story/artifact. The story is that when she wiped the blood and sweat off of Jesus his face appeared on the cloth. You'll find depictions of this in most old catholic churches and many paintings
"The Veil was owned by the Leonelli family until 1608. Pancrazio Petrucci, a soldier married to Marzia Leonelli, stole the Veil from his father-in-law's house. A few years later, Marzia sold it for 400 scudi to Doctor Donato Antonio De Fabritiis to pay a ransom demand for her husband, who was then a prisoner in Chieti."
