First of all I noticed a double page, which shows a kind of listing on the first page, which probably refers to following illustrations. This makes the page look very empty compared to the second one. Despite the long text on the second page there are hardly any dots and the text seems to be divided with slashes. The last word on every page is immediately the first word of the next page.
The second page of this pair is especially interesting, which is divided by the word ERDE and ends with a decorative pattern.
This pair caught my eye because it is a drawing and in landscape format. On this page you can find the references from the first pair.
