Tabloid photographic chemicals [L0032245]
The pattern
This still is filed under Celebrity endorsement.
Define
A named, recognizable person lends their reputation to the claim. The name is the proof.
Mechanism
Transferred authority. The reader believes the person first, the product second. Fame or office does the work a peer testimonial does not.
Verdict
The endorser is actually known to the buyer
Why it works
The dual testimonials from extreme explorers (one Northern, one Antarctic) prove the product's ultimate reliability in the harshest conditions. Facsimile signatures make the testimonials feel personal and authentic.
Steal this when
You need to prove the durability or reliability of a technical product using extreme edge-case testimonials.
