Daffy Duck is advertising a duck in Daffy Duck and the Dinosaur, so why not use common advertising slogans? (Or variations thereon).
I can’t clip together the whole, long background drawing without colour problems, so we’ll just post where the camera stops on each slogan. The cartoon is from 1939 so some of the slogans are lost on most people today.
Wheaties was the Breakfast of Champions. Fish is brain food. Dr. Pierce’s Golden Medical Discovery was a quack (duck?) remedy for all kinds of stuff. With men who know tobacco best, it’s Luckys 2 to 1. Coca-Cola is the Pause That Refreshes. I don’t recall what had more costly ingredients than the other brand. Evidently I need more duck, the brain food.
A shame it is the background artist went uncredited.
