This comic is by Ellen Forney. It’s part of her excellent collection, I Love Led Zeppelin, which you should read.
At the moment I’m really interested in comics’ potential for integrating fictional and non-fictional elements into one narrative. For example, if you were writing a short story about a hand surgeon, it’s hard to imagine reading paragraphs about the intricacies and fine points of reattaching digits without falling asleep. But with comics, it seems totally reasonable that something like the above might be part of a larger story, seemlessly integrated, and really engaging. (I should note that this is a standalone page, and NOT part of a larger narrative. But if COULD be.)
More on this later, maybe. In the meantime, check out Ellen’s blog.
