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 attractive floral imagery makes the trade card desirable to keep, perhaps in a scrapbook, maintaining brand awareness in the home.
Steal this when
When creating collectible promotional items that rely on aesthetic appeal rather than direct response copy.
