Stop racking your brain as to what this means: I found it a few weeks ago (unfortunately lost the source), and posted it without comment ’cause I thought it was an intriguing look at some history.
There was no point other than "hey, thats kinda neat — I didn’t know that."
As to other charts that DO HAVE SOME MEANING — I have a few queued up over the next few days — they will make you go hmmmmmm.

A reader points us to this collection of charts from Dow Jones, showing the Index by decades going back to 1895. Cool!
