This week sees the release of the sixth issue of Natalie Nourigat's Eurotrip sketchbook Tally Marks, from Monkeybrain Comics. In addition to the preview on Comic Book Resources, Nourigat provided ROBOT 6 with some other pages, as well as a selection of scans directly from the sketchbook. It provides readers with an idea of what her art looks like before Photoshop tweaks.
