The sign is written in Cyrillic, specifically mentioning "НАДИН" and "АВТО-МОРГА," which points strongly towards Bulgaria. The architecture of the house and the overall rural, unpaved road conditions are characteristic of small Bulgarian villages. The Cyrillic script and the specific phrasing on the sign confirm a Slavic-speaking region, likely Bulgaria given the style of the signage. I am fairly confident this is in Bulgaria.
