Nice Book for Children
As the young boy visits his aunt in the country, he realizes that the large nearby tree is filled with life from the small insects to the animals and birds. It is a built quite similar to the tenament house where his own family lives in the city.
The boy's aunt is an artist and they play many games and the boy learns how to relate the inhabitants of the tree to the inhabitants of his own apartment building. The ending of the story is nice too. The illustrations are breathtaking.
