Up in the Tree by Margaret Atwood

From chapters.ca:
This story about the adventures of two children who live up in a tree is vintage Atwood - playful, whimsical and wry. The perfect integration of words and pictures creates a coherent and delightful whole. When this charming book was first published in 1978, there was a widespread idea that it was too expensive and risky to publish a children's book in Canada. And so Margaret Atwood not only wrote and illustrated the book, she hand lettered the type! The book was created in the old- fashioned way, using only two colours that mixed together to produce a surprisingly large range of tones and textures. The delightful result reminds us that technology hasn't necessarily made things better. This facsimile edition renders intact the unique pleasures of the original.
