Interesting how the quality of diagramming is plainly worse in 2013 than in 1966. The 1966 original is more easy to read: the typeface is pleasantly wider, there is no red or blue text on a saturated yellow background. It looks better overall. One part of it is technical limitations (you can't abuse color when you print in monochrome), but it is also that the 1966 version was most likely done by a specialist, and the 2013 version wasn't.
