Owner's signature on the title page by R. "Naftali Hirsch Bleichroth", disciple of R. Akiva Eiger, and rabbi of Wielun. Page 40a contains the signature "Shmuel".
This book was one of the author's last books to be published, but it was in actuality the first to be composed by him while he was yet an adolescent. At the end of the introduction, the author writes: "I authored this book while still a child…". R. Baruch Ber Leibowitz claimed that the book was written before the bar mitzvah (age 13) of the author!
This book was popularized immediately upon publication, and has been printed in close to one hundred editions. Dozens of commentaries have been published, and studied in yeshivot to this day.
