I remember Heavy Metal Magazine from back in my teens years, and it always had and least one comic story that blew me away. For the time, it certainly pushed the envelope, and to find it still being published 45 years after its debut in digital format is nothing short of amazing.
Issue 316 is the latest issue of Heavy Metal, and the bundle includes issues 307-315 as well as a large number of trade paperback collections. I'm in for 25 bucks for the Heavy Metal Comics Humble Bundle. I've got a few weeks of comics reading ahead of me it seems. 51 titles will last a long time ;)
