Dean Garen It totally is. From drawings to simplicity of the stories it is perfect for children getting into reading. The catch is that there is a fair amount of wordplay in the stories and I think it was fun to read as an adult as well. As John Bullock mentioned: It's amazing as a bed time story book.
John Bullock I'd say it's aimed at a younger audience, but from what I gather it's kind of an anthology of short stories from his early years when he wrote for his local paper. It served well as the bedtime story book I read to my four year old for a couple of weeks.
