"Nachtkrab means something like "Raven/Crow of the night"...it's a very old German story which the grandparents tell the little grandchildren if they do not want to go to bed so early. So the grandparents or the parents told them about this Crow kidnapping all the little children who are not asleep when it gets dark outside. Afraid of this story and the spooky Crow every child wants to fall asleep immediately ;)
A very macabre story which I always wanted to illustrate. I imagined the Nachtkrab riding on something like a horse when he's to lazy to fly all the way from the dark forests into the villages..." - MetaMephisto
