Above Felix Del Marle, cartoon titled "League of Nations" (predecessor to the United Nations), as published in Le Rire (April 19, 1919). An accompanying caption reads—

The President: No more wars! Those who want to provoke will have to dread the big cannon of the League.

A Voice in the Crowd: Yes, if it's not just camouflage.
