So did the Plymouth Valiant name come from a french cartoon character?

Jesus tap-dancing Christ.

Vaillant is FRENCH for "Valiant".



Chrysler's Valiant was named for the dictionary definition: Bold, Courageous, etc.

Just like the Phord rally car above.
And the comic above.
And the Belgian short-story joker.
And every other application of the word "Valiant" or "Vaillant".

Talk about missing the forest for the trees...
