I'm very much a huge fan of the Quality and Fawcett books of the Golden Age thanks in large part to DC's revivals of their characters during the 1970's and 1980's as well as reprintings of some of those stories from those two publishers. I'm also very much a fan of the MLJ line as well thanks to Archie/Radio Comics' revivals of MLJ's superheroes during the 1960's (I first discovered them through reprints in the various Archie comics digests and through acquiring back issues of the 1960's books that they appeared in). I should also add that I'm a fan of the Nedor/Better/Standard material as well. The only stuff I'm not to fond off is much of the later Fox material and much of the Fiction House stuff.
I'm very much a huge fan of the work of the Quality staff especially that of Lou Fine, Reed Crandall, Paul Gustavson, and Al Bryant. My favorite Fawcett artists are Mac Raboy, Charles Sultan, and Jack Binder. Irv Novick, Bob Fujitani, Mort Meskin, Al Camy, and Sam Cooper are my favorite MLJ artists. I'm now starting to get into the works of Bill Ward, Lily Renee, and Fletcher Hanks as well.
