It's another informative wheel from Calvert's Distillers. "Clear Heads Choose Calvert". Look at that wise, old owl enjoying his whiskey soda! This wheel is 5.5 inches in diameter and in good shape. The outer disk has experienced some yellowing, but it doesn't seem to affected the quality. Some of the phrases don't line up properly in the slot.
We have here a timeline of some of the events of World War II along with references to where they occurred. Each phrases has a number after it and you look up that number on the maps. Easy. "British occupy Madagascar". I didn't know Madagascar figured in that war. But what do I know? The wheel is dated no later than February of 1943. I wonder if they ever updated it?
