Essential Fantastic Four, Vol. 3

By way of analogy: Lee and Kirby's collaboration in 60s Marvel was the British invasion, and their work on FF was The Beatles, then this period was the White Album. There's a 10-issue run in here that introduces the Inhumans, the Silver Surfer, Galactus, and the Black Panther. Any one of those would have been enough to make this a classic, and it's baffling they were able to create all of them within a single year.
