Sub-Mariner! The Underwater Guy!
I loved them all through thick and thin, through good stories and... LESS good stories. I was dazzled by Jack Kirby's Captain America run, Jim Steranko's revolutionary SHIELD, Herb Trimpe's Hulk and finally, later in the series, Bill Everett's last stand on Sub-Mariner.
Subby was created by Everett back in 1939, and his art and story made the character something special from the start. When superheroes took a rest in the late 40's, Subby was one of the few to make a short-lived come-back in the 50's, again with Everett at the helm. For the book's solo '60's-70's run there were many fabulous artists, from Gene Colan to John Buscema to Gil Kane, but when Everett himself came back with issue #50, things took a definite turn toward the really great.
Much of this run has just been reprinted in Marvel's long running "Marvel Masterworks" series, Volume 227 (!, and yes, I have them all!). It's hard to describe what makes these so special, but there's a lightness and wide-eyed enthusiasm to Everett's art that was different from the house Marvel style and yet perfect for Sub-Mariner. Roy Thomas's introduction tells the story of Everett's return, sadly cut short by Everett's health problems...
The BW image taken from the original art below is just a hint of Everett's style. It's really great that this material is back in print, in easy to find form. Check it out!
