New Publication in honor of my son becoming a bar mitzvah

My older son will become a bar mitzvah on Sunday, and he will mark the occasion with a siyum on all 6 orders of the Mishnah. In honor of the occasion, we have published a booklet containing Masekhet Kinim and three commentaries on it:

  1. A Tosafist commentary (possibly R. Samson of Sens [=Rash MiShantz])
  2. A short commentary by R. Yitzhak Aizik of Komarno
  3. Moshe Koppel's mathematical commentary.
Here is the title page:
