They knocked the chip off Uncle Sam's shoulder! So let's go productioneer... Let's show `em some chips!" 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 clever pun on "chips" (the chip on the shoulder vs. metal shavings from a lathe) to connect the emotional outrage of being attacked with the physical act of factory work. It visualizes the abstract concept of "production winning the war" as literal metal chips burying the enemy leaders.
Steal this when
When you can find a pun or double meaning that connects an emotional driver directly to the physical action you want the audience to take.
