I really love this style, which is the Franks Robbins & Springer, and I always liked Robbins better as an artist than a writer. All these loose, slashing brush blacks, that really barely should hold together. It gives the figures the impression of always being in motion, and it's a kind of looseness you don't see in mainstream comics anymore. (and can I just say, Frank Springer's one of those invisible supermen of comics; he's the it's-that-guy of the medium, and he may seem sedate but the man did O'Donoghue scripts, for godsake)
But at the same time, I remember finding it initially off-putting as a kid precisely because it looked so different than everything else. But, again, Nazi vampires.
