Dr. Lovelace's blotting book : with the compliments of the proprietors of the celebrated Dr. Lovelace's soaps / East Lancashire Soap Co. Ltd.
The pattern
This still is filed under Utility premium.
Define
The free thing is kept because it works (a calendar, a tool, a template) and the brand rides along.
Mechanism
Usefulness as media. Frequency of use is frequency of exposure. Distinct from a keepable card: here the object has a job.
Verdict
We can give something people will actually use next week.
Why it works
It embeds a comprehensive, logical sales pitch inside a free premium with inherent utility (a blotting book). It uses an effective 'stacked reasons' structure ('Some use it because... Some use it because...') to build an overwhelming case for the soap's superiority and ultimate economy.
Steal this when
You want to ensure your long-copy pitch is kept on a prospect's desk by printing it on a genuinely useful premium item.
