The Kodak - You Press the Button, We Do the Rest" (Life, Feb 28 1889; cropped from ad page)
The pattern
This still is filed under Price-anchoring offer.
Define
A higher reference number is shown first so the real price reads as a concession, not as a starting bid.
Mechanism
People judge a price against the first number they see. The anchor must be a real comparison or it collapses.
Verdict
We have a credible reference the buyer will accept
Why it works
The whole ad is a stack of objection removals delivered as flat statements: no dark room, no chemicals, no reloading, no learning. It then names the mechanism rather than just claiming ease - "a division of labor is offered" tells the reader exactly who does the hard part, which makes the promise credible instead of boastful. The slogan lands last, set in italic inside the body, so it reads as the summary of an argument already made rather than as a boast made up front. Putting the price in bold under the product picture pre-empts the "what does it cost" stall before the reader has to hunt for it.
Steal this when
You are selling something whose real barrier is skill or hassle, not money, and the buyer's private objection is "I would not know how to use that." Name the work you take off their hands as an explicit division of labor, then close with a short line that compresses the whole trade.
