This is the advertisement of Kadokawa Juvenile Books. Applying the technology of Lenticular printing vertically instead of horizontally, we developed a way in which a message could only be seen from a point of view of kids but hiding from a point of view of grown-ups. The messages are " Listen to a mediocre grown-up, and you'll grow up to be mediocre." " Grown-ups who tell you to study more, know nothing more." " Hate your teacher? Congratulations, you’re normal." NYADC silver award in 2010.
