Here's an ambitious project: can you fit the majority of recorded human history onto a single piece of paper?
That's the challenge that author John B. Sparks and publishing company Rand McNally took on back in 1931. The result, a chart called "The Histomap," is below.
As Rebecca Onion points out on Slate, there was a trend in the '20s and '30s to distill big subjects like philosophy, physics and, yes, history into a form that anyone could easily understand.
Rand McNally sold The Histomap for $1. It came in a handy green cover with endorsements from historians and reviewers, and it stretched to five feet fully unfolded.
