The Past is Behind Us, The Future is Ahead. Let us all strive to make the future better and brighter than the past ever was. Color poster by Gerrit A. Beneker., 1918" poster
The pattern
This still is filed under Civilian war-duty equate.
Define
A civilian act (saving, making, staying quiet) is framed as the same duty as the front.
Mechanism
Moral equate. The small act inherits the gravity of the large one. The ask is ordinary. The meaning is not.
Verdict
We need mass compliance on an unglamorous behavior and can honestly tie it to a shared stake.
Why it works
It visually bridges the gap between two major societal groups (the military and the domestic workforce) through a handshake, using aspirational copy to unite them toward a common postwar goal.
Steal this when
You need to unify distinct factions within your audience after a period of struggle or conflict.
