Ich habe gerade dieses Gemälde gekauft, vielleicht weißt du, wo es ist?

have you looked behind the couch? maybe it fell of the wall.

Do you have some background (for example, a photo of the verso), painter, date? It‘s possible it‘s a real location, but it‘s also possible it‘s (partially) fiction, as it‘s a bit of a stereotypical Alpine landscape.
