I would say the emotions and stories behind the advertisement whether it be print or tv is what makes me remember the ad. It also creates a connection when you see the product in a store. The print ad does a great job creating a story that has emotion.
This dentist advertisement uses color, or rather the lack of color, extremely well to convey the message of their ad. The copy states that the dentist does not like yellow, so why even have a yellow banana? The entirely white canvas, although simple, really works here.
