Offenberg, The dating of the Kol Bo... in: Studia Rosenthaliana 6:1 (1972) pp. 86-106: "The same type is not used in any other known Hebrew incunable... The book was printed somewhere in Italy about 1490 ... Naturally, it can indeed have been printed in Naples, particularly since the greatest part of Hebrew incunabula were published there about 1490, but it is not possible to be certain of this on the evidence of the paper alone". - A few tiny wormholes, just touching a few letters; browned; 2 small tears in blank margins repaired; one blank margin repaired.[(5758)]
