I spent a fair bit of extra time on it, because it was for a friend. Weird fact: though I’ve been a lifelong science guy (or as much of a science guy a high school dropout cartoonist really can be) I’d never seen Cosmos until this. I watched the first episode, and it was 1000% crazier than I expected (in a good/weird way).
UPDATE! I’ve turned this image into color and black and white prints, available here. If you’re into that!
