The Kodak Girl" - Kodak (Saturday Evening Post, July 4 1914)
The pattern
This still is filed under Campaign line as series.
Define
One line that can be replayed across executions so the campaign is a family, not a one-off.
Mechanism
Repeatable frame. Each ad is a verse. The line is the chorus. Recognition compounds because the structure is stable.
Verdict
We will run more than one execution and need them to add up in memory.
Why it works
Naming the character rather than the product turns a recurring model into an owned property - the headline is a label for a person the reader recognises from earlier ads, which does the work a slogan would otherwise do. The photograph shows the camera being used at waist level with the head bowed, the actual posture of taking a picture, so the ad demonstrates rather than displays. The copy runs a symmetry - the city girl's trip to the country, the country girl's trip to the city - so no reader is excluded from the promise on grounds of where she lives. Price is handled in a half-sentence, positioned as a correction to an assumption instead of an offer.
Steal this when
You want one recurring character to carry a campaign across years instead of a new idea each time. Name the character in the headline, photograph them mid-use rather than posed, and write copy that mirrors the audience's two or three variants so everyone finds themselves in it.
