Cori Mothersbaugh remembers how she used to get her books from one class to another. Starting in grade school in the 1960s and through her sophomore year at the University of Washington in 1972, textbooks would be wrapped in a heavy brown paper bag and piled up in her arms. “My generation, we didn’t put books in anything,” the 66-year-old tells Mental Floss. “We just carried them.”
By the time that finally changed, Mothersbaugh would be close to graduation. But she could take a little solace in the fact that, as an employee at the University’s campus bookstore, she was an eyewitness to a meeting between an outdoor equipment salesman and a store manager that would forever influence how kids toted their school supplies.
A leather belt. That’s what kids in the early 1900s often used to cart their school books around, securing the strap around the pile and using the slack as a handle. Sometimes the strap would be made specifically for the purpose. Other times, kids would just use a waist belt, cinching it to create a bottom-heavy contraption that was probably used by more than one child as a bludgeon.
