Odd, just looked it up and it is quite specific "any visual depiction of sexually explicit conduct involving a minor (someone under 18 years of age). Visual depictions include photographs, videos, digital or computer generated images indistinguishable from an actual minor, and images created, adapted, or modified, but appear to depict an identifiable, actual minor. " in not including cartoon images. Weird. Perhaps its done to protect paintings such as this: Two Adolescents by Salvador Dali | Oil Painting Reproduction[^]
