Fiona Staples is best known as the artist working on the Hugo, Eisner, Harvey (and probably everything) Award winning comic Saga. Yes, Saga really is that good, and the art of Fiona Staples is a significant part of Saga's success. Here is a selection from the recent run of Saga. Any text on these images are from Brian K. Vaughn.
One of my favorite things about Saga is Lying Cat, and the combination of the art and the interactions of the character is just perfect.
