If you haven’t been following John Rocco on Instagram, you might want to start. He’s been posting a lot of thrilling art from his lengthy history illustrating Rick Riordan’s books under the hashtag #PercyExtras. Included are early, rejected cover concepts for Riordan novels, special edition sketches and final art, and our personal favorite, a collection of illustrations he needed to use a model for . . . himself!

We have to admit we’re disappointed he didn’t share the photo he took to model for this giant in a special edition of The Sword of Summer. What a scowl he must’ve put on for that one!
