Willi is a little Danish kid who has many adventures, but today he is mad.  He doesn't want to do things or talk to people and he holds on to his anger.  But then he meets an angry little girl, and unexpectedly, they help each other stop being mad!.  At the end are 2 short "how to" pages about how to make mad and happy masks. Approximately 7.5 x 7.5 inches.  13 pages.  Twenty-one sides include 1 or 2 short sentences and dialogue.  Very good condition with minor nicks on the covers, and tag residue on the back cover (see picture).
