Epreuves des caracteres de la fonderie de Claude Mozet
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
The use of a blank flyleaf is a standard bookbinding practice to protect the title page and add structural integrity to the bound specimen book.
Steal this when
When designing the physical structure of a premium book where protective blank pages convey luxury and careful binding.
