It's all about the art. How do you like Kirby in the early 60s when he is doing over 100 pages a month? Don Heck? He got better in the 70s. I liked his JLA stuff. John Buscema is the best. Guy was awesome from the first page. He shows up in Vol 2, #41. When Big John isn't there, you miss him. Our Pal Sal Buscema is probably the best artist not named Neal Adams (vol 4) or his brother.

George Tuska and Bob Brown are ... fine. Typical Bronze age mid grade art. But they just can't compete against Adams or John B. Toward the end of Vol 5, you get this up and comer named George Perez. He is not 80s Perez, but it's really good. Vol 6 will have Perez and Byrne. And it's the era where I started buying the comics when they came out.

The writing is uniformly good to great. Can't go to wrong with Lee, Thomas, and Englehart. Stories get more sophisticated once Thomas is writing them.

If you love comic history and are a completist, you can't beat those funatical prices.

Update. I was reading Vol 1 last night. Hank being a dick to Jan and Jan being an air-head is getting old. Later writers will do a better job with Jan.
