Either in season 4 или 5 Dwight briefly holds up a German children's book. Does anyone have any idea what the Название is?

Years ago, when I was very young, a friend of mine (who is part German) had that very same book that Dwight displayed. I just about fell over when I saw it. The illustrations were very vivid in depicting all the awful things that would befall disobedient kids. For example, I clearly remember seeing a thumb-sucking boy having his thumbs cut off by a scissors (huge!!) wielding adult. Then a child caught playing w/matches was reduced to a big pile of ashes.
