Spratts patent "pure fibrine" poultry meal & poultry appliances / [Spratt's Patent]
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 vibrant front image sells the dream of a diverse, thriving, and peaceful flock. The back pivots immediately to practicalities, using warnings against 'pungent compounds' sold by greedy tradesmen to position Spratt's as the honest, common-sense choice.
Steal this when
Selling a premium commodity staple by contrasting your purity with competitors' alleged shortcuts.
