Cigainero, 1940s or 1950s?

Eight siblings line up for a photo in front of a house.

The black-and-white photograph depicts a group of eight people, seven men and one woman, standing closely together in front of a brick building with large windows and a tall evergreen tree on the right side; the men are dressed in similar attire, wearing shirts, ties, and trousers, with some in suspenders, while the woman, positioned second from the right, wears a dark dress and a wide-brimmed hat.
