Just curious.
Just a WAG - beefiest = Bart Sears, slenderest = Lee Moder?
Jim Lee doesn’t know how to draw a regular male so I assume his Bat and Supes are probably the beefiest.
Beefiest Superman: Jon Bogdanove
Beefiest Batman: Bruce Timm
Slenderest Batman: David Mazzucchelli
Define beefiest. In the 50s and early 60s, Superman and Batman were generally drawn robustly, with barrel chests and torsos, but didn’t have the fantasy-level muscle definition of more current artists.
Also, this thread cries for links to example art.
Beefiest Batman and Superman: Frank Miller
Ed McGuinness draws everyone as beefy and puffy as Macy’s Thanksgiving Day Parade balloons, so he’d have to be up there with Bart Sears, as well as Sam Kieth, Simon Bisley, and Kelley Jones (who have all drawn Batman at various points).
Oh, and as for slenderest, probably Japanese artist Yoshitaka Amano, who drew very effeminate, androgynous, almost spiritlike versions of both characters in posters released by DC Direct.
Alex Ross, noted for his photorealistic style, draws a pretty stocky Superman and beefy Batman. Can’t think of the slenderest.
McGuinness is who I came in to mention.
Frank Quitely draws them both rather seriously pumped, as well. Unlike McGuiness (or Bis, for that matter), he does do actual slender characters, at times, too.
wayne Boring was the definitive Superman artist during the 40’s and 50’s. He started out as a staff artist for Seigel and Schuster, then was hired directly by DC Comics in 1942. He drew both the Superman newspaper strip and the comic book stories until 1948, when he left the strip and drew the comic books exclusively. His Superman was dynamic and muscular and was most notable for his brooding look.
Another vote for Wayne Boring. That man drew Superman with a chest you could … well… bounce bullets off of, I guess…
Beefiest by far: Mike Sekowsky, especially toward the end of his run pencilling Justice League of America. Supes chest was about the width of a Mack truck, and the “S” was always too big. Sekowsky did good work in the early JLA, but toward the end of his career, he just lost it.
