I Want You" - U.S. Army recruiting poster (1940 reissue)
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 relies on the proven, intense personal connection of the original Flagg illustration. The breaking of the fourth wall creates an inescapable demand that feels targeted squarely at the individual viewer, which remained highly effective for WWII.
Steal this when
You need to make a demand or request feel intensely personal and impossible to ignore, forcing the viewer to confront the message directly.
