A "spooky" image of a priest executed for treason over the Gunpowder Plot has appeared on a 17th century book thought to be bound in his skin, it is claimed.
Auctioneers said the face of Father Henry Garnet could be seen peering from the cover of the "rare and macabre" book about the Jesuit priest's death.
The item will go under the hammer at Wilkinson's Auctioneers in Doncaster, South Yorkshire, on Sunday.
