Back ache quickly relieved by Carter's smart weed and belladonna Back Ache Plasters.
The pattern
This still is filed under Keepable trade card.
Define
A small card people keep (pretty, useful, or collectible) that carries the brand after the encounter.
Mechanism
Retention object. The gift is the media. Recall is paid for by usefulness or delight, not by repetition.
Verdict
We can put a physical or digital keepable in someone's pocket and they will not throw it away.
Why it works
Uses an appealing, unrelated wholesome illustration (children playing) on the front to ensure the card is kept, while placing the hard-selling medical claims and detailed copy on the back.
Steal this when
You are creating a trade card or collectible item where the front must be visually appealing enough to save, and the back does the heavy lifting of the sales pitch.
