When you've got fresh order of salty fries, sharing French fries with others is just something that tends to happen, whether you're willing to share or not. This is precisely what this McDonald's ad represents, showing a bunch of hands that are dipping into a container of McDonald's fries.
The clever ad plays with positive and negative space and since the brand's colors and logo are so well-known, it doesn't take much to get the message across with this visually powerful ad. However, there is a very small amount of type on the ad, printed on one small fry, which reads: "More Fries, Less Friends." Although it's pretty sneaky suggestion, it is a way to ensure that you'll be able to enjoy more of the fries yourself.
