Farmers, Uncle Sam asks you...To get Ready for the Census Taker" poster
The pattern
This still is filed under Recruiting duty offer.
Define
Join us, framed as who you become, not as a job listing.
Mechanism
Identity offer. The role is a self. Benefits are secondary to the person you will be after you say yes.
Verdict
We are recruiting into a hard, proud, or transforming role: service, craft, a company with a real culture.
Why it works
It personalizes a bureaucratic process by having "Uncle Sam" directly ask for the farmer's help. The imagery of orderly, abundant fields implies that the census is part of managing this national bounty.
Steal this when
You need to encourage compliance with a potentially tedious administrative task by appealing to patriotic duty and organization.
