Well that image is from http://www.parthenongraphics.com/ .  Those aren't really for printing, I don't think; they're images of posters you can buy.  Incidentally, I was wondering if anyone has found a free, small program for creating timelines.  Perhaps a plugin/extension for Open Office Impress would be nice.  I would ideally like to input dates and corresponding information into power point presentations which would be enhanced with such a feature.  If one does not exist, then I wish someone would make one.
