Book of Type Specimens, Comprising a Large Variety of Superior Copper-Mixed Types, Rules, Borders
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 combines a vast visual library of display faces with strong technical arguments (the Point-Line system and Copper-Mixed metal) that appeal to the practical and economic concerns of the printer.
Steal this when
You need to market a product that is both aesthetically diverse and technically superior, requiring detailed explanation of its engineering alongside visual proof.
