The Visual Aid book series is chock full of fun and fascinating infographics that explain everything from the space race timeline to the relative sizes of the dinosaurs. And they've distilled their visual information onto handy posters.

These posters come from Visual Aid and Visual Aid 2, and are available as posters from the Visual Aid shop. Incidentally, they also have useful posters if you want to know how to make a balloon animal, how to play Cat's Cradle, or the different processes for mummification.
