I love the drawing mistakes on old comic book covers. Here (above) a tiny car drops off a dead man who, if he were standing upright, would be taller than the door. His girl, who has a gigantic left leg, backs up to a miniature staircase. It's all goofy, but it works...for me, anyway.
I don't mind mistakes when they're funny.
I guess that's why I like early comics. They're full of mistakes! How do you like the hand in front of the girl's face or the inappropriate (and no doubt unintentional) grab?
The best artists eventually figured out perspective but their later work never had the guts of their earlier stuff. Even famously smooth DC artist Carmine Infantino (that's his work, above) had trouble with perspective when he first started out. I like his early work better.
It's my belief that gutsy but primitive art prompted writers to write better stories, but I guess making the argument for that would require a separate post.
BTW: I've got a lot of work to do around the house so my posts might be a bit irregular for a month or so. I'll get on a normal schedule just as soon as I'm able.
