Here's an Extra $50, Grace - I'm Making Real Money Now!" (Popular Science Monthly, June 1920)
The pattern
This still is filed under If-then promise.
Define
A conditional contract: if you do this, you get that. The sentence can be tested against the reader's own case.
Mechanism
Specificity does the persuading. The if names the action. The then names the outcome. Hedging kills it.
Verdict
We can name both the action and the result without adjectives
Why it works
The scene is overheard rather than narrated - the reader arrives after the payoff and reconstructs the whole before-and-after from one line of dialogue, which is quicker and more believable than being told. The money is physically present in both the illustration and the headline, and it is being given away rather than boasted about, so the proof of the raise arrives as an act of generosity. Naming the wife and crediting her - thanks to you and the I. C. S. - recruits a second person to the sale by handing her the argument to make. The occupation checklist lets a man declare an ambition he may never have said out loud, at the cost of a single pencil mark.
Steal this when
You are selling a long, effortful investment whose payoff is distant and abstract. Dramatize one moment after the payoff has already landed, write it as dialogue, and let the reader infer the whole journey from a single sentence.
