Campaign ads of yore
The most famous of this batch of ads from Johnson is the "Daisy" spot, where a little girl haltingly counts up to ten while pulling petals off a daisy, followed by a countdown to a nuclear explosion as camera zooms in on her face. However, the ad that really wowed me was the Glen Canyon Dam spot, which directly addressed the public works=creeping socialism meme coming from the Goldwater campaign.
Quite a change from the "let's see how many talking heads we can cram into 30 seconds" style of campaign ads, no?
