Don't let Idle Cylinders Jam Production. Keep 'Em Rolling!" poster
The pattern
This still is filed under Us-versus-them positioning.
Define
The buyer is invited into a side. The product is what we use. The named other is what we refuse.
Mechanism
Identity contrast. Choosing the offer is choosing a group. The out-group does as much work as the claim.
Verdict
The category is crowded
Why it works
It uses a clear and immediate visual metaphor. The hourglass represents time and the flow of necessary war materials, while the stuck cylinder perfectly illustrates how a seemingly minor oversight (not returning cylinders) causes a massive bottleneck in the broader war effort.
Steal this when
You need to convince people that a small administrative or logistical action is vital to a much larger, important goal.
