[1] The magazine was named after José Sixto Álvarez (1858–1903), writer and journalist who was notable for his humorous texts, apart from having been the founder of Caras y Caretas.

[1] The magazine was founded with the purpose of continuing the editorial line of Caras y Caretas that had significantly changed since the death of Sixto Alvarez in 1903.

[4] The magazine covered a wide range of topics, some of its permanent sections were theatre activities, provinces, women, Montevideo, readers' letters, children's literature, horse racing, other countries' traditions and costumes, and everyday life, among others.

[5] The rise of art nouveau in Argentina in the 1900s influenced not only magazines' visual styles but facades of private houses, and was quickly adopted by the middle class.

[1] That aesthetic renovation was also visible on typography, illustration and design of Fray Mocho, as well as advertisement, facades of public buildings and even clothing in the Argentine society of that age.
