I agree that Jakow is another possible candidate for the J. Adler who signed the album--he's a bit younger than I would have expected for a gymnasium student, but not by enough to make me doubt his candidacy. Also note that you'll find him listed with the same birthdate as Jakob Adler; there's a Jakub Adler, with a different address, also born in 1928, who you'll want to keep an eye on as well.
