Als Herr Martin durchsichtig wurde (The day Herr Martin turned invisible) / Paul Maar. Illustrations by Katharina Grossmann-Hensel. - Hamburg : Oetinger, 2011. -  sheets : Mostly illustrated |
Yikes! Herr Martin is becoming invisible and nobody knows how to help him. But not being seen is not all bad. Especially not when Frau Sawitzki sits on the chair without noticing that Herr Martin is already sitting there.
Recommended for ages 5 and over.
