A small documentary film on the Rialto fish market in Venice. The Loggia della Pescaria overlooking the Grand Canal looks like an ancient place. Yet this building, under whose shadow sellers and buyers flock, is rather recent. It is in fact an early 20th-century building, built by architect Domenico Ruspolo together with sculptor Cesare Laurenti, in the neo-Gothic style. So when Pierino Mainardi films in 9.5 mm the activities that take place in this place, on 11 December 1930, the building is barely twenty years old, even though the fish market in the lagoon city has thrived for centuries. But Pierino is mainly interested in showing the men at work and in filming in detail, and probably for promotional purposes, the Mainardi family's fish business, shown frame by frame and caption by caption. And the M in the framed boxes refers precisely to the surname Mainardi, the E to his father Emilio, and the F to his sons, including Pierino, whose only interest, however, is in the camera and women. This time with the camera he does a nice service to the family business.
