Documentary about the Minas Gerais photographer Assis Horta, who immortalized the architectural heritage and society of Diamantina. The great impulse of his career came in 1943, with the Consolidation of Labor Laws, promulgated by Getúlio Vargas. By making mandatory a professional card with photo, Vargas gave the push that the working class needed to enter Horta's photographic studio. In the years that followed, the photographer portrayed hundreds of people. In 3x4 or full-length, many took their first portrait.
