This early book carrier is a wooden handle attached to cloth straps. This type of carrier was used by children from the mid to later Victorian into the early 1900's. Here's a chance to buy a wonderful school house treasure from the past.
By placing a book, or books, between the loop of the straps, the handle was then turned, winding the straps tightly against the book and handle. A lock mechanism with metal tab, would flip to latch to secure the books for ease of carrying. To remove the books, the tab was released and the handle was unwound the opposite direction.
The carrier is a wooden handle in natural wood, Smoothed with years of handling. The metal parts are black enamel. The straps are a blue with brown edge woven tape.
Straps are soiled and one is a bit twisted being folded in storage. Still workable.
