The letter comes from the collection of Zygmunt Urbanyi – composer, conductor, music reviewer and artistic director of choirs mainly in Bydgoszcz. Its author is Feliks Nowowiejski - composer, organ virtuoso, conductor, teacher and professor at the conservatory in Poznań. The list of his works is very long and includes operas, oratorios, masses, symphonies, organ and solo concerts, choral works and even music to ballets and theatre plays. Two works by Nowowiejski gained the greatest popularity before the Second World War: the oratorio Quo vadis and Legenda Bałtyku [The Legend of the Baltic Sea] presented in almost all opera theatres of the Second Republic of Poland. However, he is best known as the author of the melody to Maria Konopnicka’s poem Rota. Double-sided white card, on the first page, in the upper left corner, printed sender’s address in black ink.
