This is a rather clever book. It does not have any words, only pictures. The images are in sets showing a thing at different times and so capturing the evolution from one aspect to the other. It may be a drawing of a town during the day and then during the night; or an egg and a chicken.

It is nicely done, interesting to look at, gently humorous and overall an enjoyable book. This would be the equivalent of a good quality children's 'coffee table book'.
