When this timeline came on line the ‘pre-history’ section was light on illustrations; no longer. From the Big Bang (well, from a teensie fraction of a second thereafter) to 1899, the pictures are in place with 1900-1906 to be sorted next; the years 1907-1912 are already illustrated. Crazy modernists among you will find plenty of text and some illustrations for the 1920s and ’30s with a full complement of pics to follow. Enjoy.
