If you're reading a blog called "Culture High, Culture Low" (and let's be honest, you probably aren't), you hopefully share some of my interest in a wide range of artistic output. I don't really think there's a hard line dividing "high" and "low," and even if there is, I think it's really limiting to focus on one or the other. I'm a fan of ultra-cerebral modern and contemporary art as well as visceral pop culture like pop music, pro wrestling and, of course, comic books.
I'm also a big fan of artists working across the traditional lines of "high/low" culture and/or combining more than one form of art. A great example of this would be these costume designs for a 1969 production of Shakespeare's Julius Caesar, created by Jack Kirby, who is widely considered to be the most important and influential comic-book illustrator of the past 50 years at least.
The designs are classic Kirby, and are really only missing extreme foreshortening and some "Kirby Crackle" to complete the effect.
