The first interesting thing I noticed was that at the end of a chapter there always was an illustration summarizing what the reader just learned. The next chapter was then introduced with a title page also catching the readers eye with an image representing what can be expected. An example are the pages 192/193.
Pages 182/183 caught my attention because they do not only consist of two regular sized pages but ones that can be folded. In this way a rather large image can be viewed in detail and does not have to be reduced.
Lastly I chose the pages 272/273 because here the reader only has an image in front of them without any explanation. The image is placed in the upper area of the pages leaving space that could have been used for a description of the image. I think that the space was left empty in such a way that the reader can write down his own notes.
