Pix'n Love announced that the book became available starting 25 April 2012. However, various setbacks have delayed the official publication of the book. There were also some licensing issues with some of the book’s contents, according to a translator working on the English version.
On 3 August 2013, a few members of Sonic Team and SpecialEffect, an British Charity, signed one of those books during the Summer Of Sonic event. That book that was signed by those persons went on an Auction on eBay which it would give out all of it's profits to the Charity. The Bid ended on 24 August 2013 at 10:39 AM EDT (2:39 PM UTC) at US$233.91 or £150.
The book was published on Amazon.com on 6 September 2013 after a possible one year delay from getting the retrospective published. However, it was published as an hardcover.
