Un Giorno in Venezia (A Day in Venice) Op. 25, music composed by Ethelbert Nevin for piano, published by The John Church Company in 1898. The 4 short pieces are:

Alba (Dawn)
Gondolieri (Gondoliers)
Canzone Amorosa (Venetian Love Song)
Buona Notte (Good Night)

Each piece is illustrated, but I did not see any mention of the illustrator's name. The booklet is in very good condition. The owner wrote her name on the title page and made notes in pencil on some of the pages.
