This striking medal is a representation of the Shroud of Turin. The image on the shroud is the reverse image of a man, considered to be Jesus Christ.
The medal's image is a vision as mysterious as the actual shroud, but the man's face is visible.
The Catholic Church has neither denied or endorsed the actual shroud. So, faith is the guide to belief.
The medal measures about 1 inch high by 5/8 inch wide.
