1925 and 1926 Notre Dame lot of 12 student tickets (college basketball and football)

Lot of 12 different numbered, undated original Notre Dame Athletic Tickets from the 1925 to 1926 season. Some or most probably were basketball or football game tickets but the sport is not printed on them. The tickets refer to a book and therefore probably were issued to students who, unlike the general public, sat in designated sections and not specific seats. PRISTINE CONDITION.
