What does a record of 4000 years of human history look like? A freaking huge image. This histomap was published by Rand McNally in 1931. It was printed on a five foot long folder, folded into a normal sized envelope and sold for a dollar each. Vertical axis on the map shows the time, while the horizontal shows the progress of various civilizations of world history.
Being published in 1931, it is pretty outdated and is liable for some historic inaccuracies, but the charm and the broad strokes of history stay on well.
