 An early publication of the work, known as ""Estudio para Guitarra" de Rovira" was published by J.A.Medina e Hijo in Argentina probably in 1913, or with complete certainty before 1925, when the publisher ceased activities; which is attributed to Spanish guitarist Antonio Rubira.Guitarist and composer Isaías Sávio (Montevideo, 1900 — São Paulo, 1977) who published the work in 1959 titled "Romance de Amor (Estudo em Mi) Música de Antonio Rovira (Segunda metade do século XIX)" has published information which also cites Antonio Rubira as author (see "Violào e Mestres" Junio, 1966 / Sào Paulo, Brasil)
