WWI & 1920s vintage geography school books w/ antique maps & war photos

Lof of four early 1900s vintage schoolbooks, geography and World War I history. The Nations at War is dated 1917. The three geographies are dated 1920 and 1927.

These four books are a wealth of old maps (many in color), photos and other illustrations (some color plates).

All were children's school books and show it, with pencil marks, soil and spilled ink to some page edges, water spots and wear to covers and some pages. We haven't checked these for missing pages, but would expect to find a few missing pages, too!
