I previously found a great site where you could read the full issues of Marvel's FOOM fanzine, but dammit, I can't find it now!

Particularly the first 4 issues, that are designed by Steranko, and have some great covers and pin-up pages by him.

Here's a sampling. Steranko did the first 4 issues (of 22 total).

Even without Steranko, they were a nice collection of pin-up pages of artists just starting out at Marvel, like Rich Buckler, George Perez and John Byrne. As well as photos every issue of Marvel's artists, writers, editors and production staff working there, just hanging out in the Marvel bullpen.
