Hood's advertisement
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
Pure emotional appeal using cute animals. It's designed to be kept and displayed, keeping the brand name in the home.
Steal this when
You need a low-cost, high-retention giveaway item that relies entirely on charm rather than copy.
