Queenn Victoria Coin; Mellin's Food Limited
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
Novelty items that look like money have high retention value. The user will keep it, and the reverse side (not pictured but noted) advertises Mellin's Food.
Steal this when
When creating a physical keepsake for a promotional campaign.
