Original day planner from a medicine manufacturer. It has been filled out on most pages. There are some notes and addresses including several feldpost numbers throughout the book. There is some mention of Poland in September 1st as well as mention of troops reaching Warsaw on September 8. There are some separate pieces of paper inside. The calendar is basically a spiral bound notebook inside a hard cover. Some of the pages are a little torn near the binding. There may be some missing pages but none that I noticed while flipping through. It measures about 8" X 4 7/8".
