In January 1953, Mexican photographer Nacho López conducted a unique social and cultural experiment featuring actress Maty Huitrón.He asked Huitrón to go to the market while he pretended to leave to fetch more film.Instead, he hid and followed her, photographing her candidly as she walked down Madero Street in Mexico City.

The series, titled 'When a beautiful woman walks by Madero Street,' captures the reactions of ordinary people, particularly men, to the presence of a well-known actress in everyday urban life.

López's approach stood out because he avoided hypersexualizing or overly stylizing Huitrón, focusing instead on genuine moments and social interactions.The series not only highlights Huitrón's presence but also provides a lens into the cultural and gender dynamics of Mexico City in the 1950s.

Over the years, Huitrón has described the experience as unique and respectful, emphasizing the photographer’s skill in portraying authentic scenes without exploiting the subject.

The collection remains significant in the history of Mexican photography, exemplifying López’s dedication to documenting ordinary life while also capturing the nuances of public perception, urban culture, and human behavior.
