Propaganda
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.
Mechanism
Controlled display. Same conditions, side by side, no adjective required. The sample is the sentence.
Verdict
Buyers choose by eye or by hand and we can put the real thing in front of them.
Why it works
It is a purely utilitarian library binding, evoking a sense of historical artifact and academic seriousness.
Steal this when
You are trying to evoke a sense of hidden, esoteric knowledge or a historical archive in your design.
