Enrico Caruso Autograph Letter Signed to his son, Rudolfo, with self portrait. Based on Caruso's reference in this letter, Fofo, as Rudolfo was known, was studying in an academy in Florence at the time. Caruso begins by criticizing his son for not writing in his, "own hand writing, whether it is good or bad. I hope I will soon receive such a letter, so I will be happier...." Caruso infers that his son likes boarding school then offers advice for success. "Be serious and make everyone love you, especially...the superiors (higher grades)...." Caruso does not know when he will see his son but offers to send stamps and hopes "to hug" him in "May or October." He ends with an expression of love, then signs, "Papa." Caruso sketches his face in profile under, "Papa." The four page letter was penned on a folded card measuring 3 1/2 x 3 inches closed, with decorative center fold perforation. The card comes in a card folder with a greeting in English on the cover. Perhaps Caruso wrote to his son from England or America.
