Or rather, commissions without permission! Any artwork about Stephanie publicly available on the Internet done by professional artists. If it's someone's commission, ask permission and put it in the commissions section, but if the artist themselves made it publicly available, or it's already in a general image section devoted to Steph, you can put it here.
I found most of these thanks to http://comicartfans.com/, a great collection of comic art!
