This special 96 page giant sized anniversary issue was significant for two reasons.
Firstly, it effectively launched DC’s new timeline, which sought to streamline the company’s somewhat fragmented and convoluted history into a neater chronological order. This also was a lead in to the next big DC event, named 5G, the latter name also signifying the fifth age of heroes. As part of this new timeline, Wonder Woman is revealed to be the very first hero in the DC Universe, pre-dating the arrival of Superman on Earth.
Secondly, as part of this new timeline, the Wonder Woman book reverted back to it’s original issue numbering from this point forward.
This special issue saw a number of previous writers and artists return to the book to provide standalone stories, pin ups as well as a number of variant covers depicting Wonder Woman through each of the previous eight decades she has been published.
