Anyone notice that the odd placement of the Munchkin Country on the left side and the Munchkin Country on the right side of many maps of Oz may relate to how the story of The Wonderful Wizard of Oz flows?
Take a timeline of events. If you placed the events of Wonderful Wizard on one, all events would be flowing left to right. Now, Dorothy arrives in the Munchkin Country, which would put those events on the left side of the timeline. Moving further down the timeline, we'd get to the Emerald City, and further on right from those events, we go into the Winkie Country.
This probably has nothing to do with the incorrect maps, but I thought it was an interesting observation that I've had for awhile now. Now it's out and on the blog, and I can move on with my life.
