Hood's pansy
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
The novelty format (die-cut flower shape) makes it highly collectible and likely to be kept rather than thrown away, extending the lifespan of the advertising message.
Steal this when
You are creating a physical premium or giveaway and want to ensure it is kept by the recipient by making it a beautiful, novelty object.
