This pocket-sized dictionary is 100 years old. It was printed in 1917 by Funk & Wagnalls Company in New York. Then it was presumably used in WWI, and about 70 years later my mom picked it up at a book sale. I wonder if in between it was picked up and used in WWII.
The interior translates common military terms into French for practical use by the "Belgian, British, and French armies." It even translates geographical terms in a pictographic way.
Quite the fascinating read!
