First we got Day 16 with the 6 comic book heroes, 3 from classic European comics and 3 from Japan. If you click on the image you’ll see the larger version, and you’ll find from left to right: Diabolik, Kenshiro, Corto Maltese, the Client (i.e. the guy that commissioned the image, AKA “Vultus”), Lupin III, Tex Willer and Captain Herlock.
Then we’ve got Day 17 with “The Magician”. This guy is from a setting I believe the client is creating himself, and he’s quite powerful but also very afraid and insecure. As before, click the image to view a larger version.
