J.M. Boas & Co. Nieuwe-Heerengracht 41 Amsterdam. 'Patee'-rijwielen met ondoordringbare 'Chase' banden
The pattern
This still is filed under Demonstration ad.
Define
The product does the arguing. The viewer sees the thing work, not a slogan about the thing working.
Mechanism
Proof by performance. The claim is the action: a visible, testable result the reader can replay.
Verdict
We can show a result in seconds
Why it works
It dramatises a negative attribute - the puncture that will not happen - by staging the attempt to cause it, which is the oldest form of product demonstration and needs no copy to explain. Three faces all looking at the same object drag the reader's eye to the wheel and model the reaction the advertiser wants. The dealer name sits above and the product name below, so one sheet works as the shop's poster and the brand's poster at the same time.
Steal this when
Your claim is that something will not fail. Show a person actively trying to break it in front of witnesses, instead of writing the word guaranteed.
