Collects Journey Into Mystery #83 - #112. Not all classic Marvel (tho' I loved them as a kid). Some of the early stories are weak and art by Sinnott and Heck is interspersed with some great Kirby. It's all Kirby from #101 on though and then it starts to become excellent. Issue #112 is a major '60's Marvel.
