As I think I said on another thread, BIG BANG COMICS was about my favourite retro Golden Age/Silver Age superhero publication. So it's amazing to have someone posting here who was involved with bringing me so much satisfaction.
[My one quibble is that whenever I go on eBay or other sites in search of back issues for BING BANG COMICS (1940s "whites" published by Maple Leaf), the search engine assumes I meant BIG BANG COMICS.]
Behind BIG BANG, I would put Alan Moore's SUPREME and 1963. And then ASTRO CITY.
Also a few years back, Marvel put out a comic called AGE OF THE SENTRY. The Sentry being, apparently, another Marvel counterpart of Superman. I didn't know anything about this character, so I read this comic book cold. That series ran for six issues, but I hoped it would be an open ended run. The stories were clearly meant to pay tribute to the classic Superman comics. "Tribute" I say, although they may have been intended to mock Superman--but the way I read the comics, I never got that feeling. I felt like this short-lived series was written and lllustrated with unbashed love and admiration for classic DC (one sees a lot of DC comics that betray a love for classic Marvel, but rarely Marvel showing any respect for classic DC).
I understand that The Sentry as a character within the Marvel Universe is viewed with great contempt, but I've never read any of those comics. To me the AGE OF THE SENTRY demonstrated that modern artists and writers could go back to the classic motifs and do a good job of it. Whereas, usuallly I find most tributes to the past miss the mark completely.
