Marvel’s increasingly popular Guardians of the Galaxy are set to get a deluxe art book retrospective in April.

Guardians of the Galaxy: Creating Marvel’s Spacefaring Super Heroes is written by Marc Sumerak. It delves into the nearly 50-year history of Star-Lord, Drax the Destroyer, Gamora, Rocket Raccoon, Groot, and other members of the Guardians lineup with exclusive interviews, artwork from five decades of comics, and a cover from Dale Keown. The book will release on April 4 and has an MSRP of $45.00.

The book hits shelves a month before the Guardians of the Galaxy Vol. 2 comes to theatres (see “'Guardians of the Galaxy Vol. 2' Spot from Big Game”).
