Here's another Chart of Knowledge wheel, this time of Asia and Europe. It's packed with information. It looks like the folks at the Chart of Knowledge Company of America drew these maps up from memory. Mongolia is almost as big as China!
This wheel is pretty old. Just look at the countries: Siam, Persia, Jugo Slavia. I don't know what that thing above Tibet is.
This wheel is ten and a quarter inches across. I like the colors on the Europe side. That's about it for this wheel.
