Handwritten letter and signature of Rabbi Shlomo Wolba after seeing the innovations of Rabbi Avraham Rosenberg's teachings presented to him in handwriting.
The genius apologizes for not being able to see the full extent of his innovations 'because I am so busy with my work with the many that I have no time left to look at books that are not according to my work needs', and adds that by publishing his book he will get a respectable job of teaching Torah
