This is a photograph of a contact sheet containing multiple individual images. It displays a series of small black and white photographs laid out consecutively in strips, depicting various scenes. The scenes include industrial settings such as train tracks and large storage tanks, construction sites with workers and scaffolding, street views with buildings, as well as candid moments capturing everyday life. The images capture moments of human activity, architecture, and possibly some form of industry or transport. The characters "UBA" prominently appear on one of the vehicles depicted. Numbers are marked along the frames with handwritten annotations, and a name "SANTIAGO" is inscribed at the bottom.
