Lots of art by Christian Alzmann, Doug Chiang, and Ryan Church. There's lot of arts and quotes from the artists and incredibly tiny type throughout because of all the information they wanted to include in this making of.

The Mandalorian follows the adventures of galactic gunslinger Din Djarin and the Child as they traverse the outer systems of the galaxy and evade remnants of the Empire. Readers will encounter early visual and conceptual ideas for these new characters and unexplored frontiers, filled with crime syndicates, bounty hunters, and smugglers; gritty, lived-in cantinas and spaceports.
