George H. Libby knapsack, ca. 1861
Soldiers often found rigid knapsacks, issued early in the Civil War, uncomfortable, especially during long marches. They often discarded them, favoring the soft-sided version issued later.
Stenciled on the canvas is "George H. Libby Co. …" The company identification is unreadable. The name also appears in ink on the bottom of the knapsack. Libby may have been from Portland.
