A big BIG ARTBOOK with the work of Tom Hunter a.k.a goblintom if you follow him on IG. It's 205 x 295mm (for reference, it's probably bigger than your whole face), 140 full-color pages of exactly what the title says; Magic, Metal, Mayem (and also, heaps of muscles). The book also has an in-depth commentary/interview track throughout.
This book will either make you want to draw, or respec to barbarian class. Maybe both.
