@Kururu_luva: I agree with your explanation, but I wouldn't have put in the same way, lol.
Basically I think it depends on the context of the work. If the original purpose is to entice, then I wouldn't want it anywhere where I could see it. Otherwise, if it's to inform me of something, history, or otherwise, then I couldn't really argue against it.
And even though medical texts and diagrams are 2d, couldn't you also compare them to 2d ero publications as you've compared the 3d subjects? (
