A journey through time for the 40th anniversary of the Ninja Turtles! From the very first sketches of the Nija Turtles by Kevin Eastman and Peter Laird, to the covers of the last reissues of anniversaries, go back in images to the origins of a monument of the history of comics. This album takes over all the covers of Eastman's original series and Laird's complementary works made in collaboration with others, as well as many contributions from the greatest artists in the industry. To close this retrospective collection, this book is printed in color. This seventh (and final) volume was specially designed to celebrate the 40 years of existence of the Ninja Turtles and allows us to understand, with images in support, how the Turtles have moved from simple sketches on a paper to the status of international icons of the comic book.
