Mantel is a town of 2700 people and is best known for its nature preserve, Naturwaldreservat Gscheibte Loh, and its castle, Schloss. The town was first mentioned in official documents in 1212. I think this card is a photo of a character from the HBO show Game of Thrones, but the card doesn't say whether it is or not. It does mention a copyright from HBO. I've also never watched Game of Thrones  so I wouldn't know.
