ENRICO CARUSO A.L.S. on the verso of a postcard addressed to his patron, Sybil Seligmun, Florence, July 23, 1910, in Italian. Caruso sincerely apologizes for having misunderstood the time for their rendezvous, adding: "...Now I'm sure that next week I'll be there, to see also my family...but it is not possible to come on Sunday... " Penned just beside a full-length photograph of Caruso in character. Some cracking and wrinkling, overall good. $350-450
