This Pepsi ad from the 1950s has entire sentences telling you what this drink is and how you should drink it.
The ad has a headline, not one but two slogans, and even has body copy. And it tries very hard to sound polite, urbane, sophisticated—the 1950s idea of classy. Pepsi isn’t just a soda: it’s a light, sociable refreshment.
To pull this style off, think calm, cool and collected. Choose your product, and tell your reader why it is the right choice, but don’t show too much emotion—you’re too classy for that.
