The pattern
This still is filed under Specimen as proof.
Define
A specimen (type, material, finish) is shown so the product proves itself under comparison.

Verdict
Buyers choose by eye or by hand and we can put the real thing in front of them.
Why it works
It is the ultimate "show, don't tell" demonstration. The book itself is a masterpiece of precision printing, proving to the buyer that these complex chromatic blocks can actually be registered perfectly to produce spectacular results.
Steal this when
You are selling a technically complex, premium product whose primary value is aesthetic; you must prove its worth by producing a jaw-dropping demonstration of it in action.
