The page reads best when each object keeps its own scale.
A map wants labels, borders, and route logic. A lunar module wants structure, shadow, and landing gear. A cloud disk wants the limb of the planet and the texture around it. Each object below keeps to the kind of reading it can support.
The examples are grouped by material type rather than by tone. That makes the page move from deep space to city plans, then to Earth, Mars, planets, and print without losing the source trail.
The result is a page that can hold a lot of material while still staying specific. Every case names the object, the collection, and the page that carries the record.
What matters most is the object itself, followed by the credit line that tells the reader where it came from.
