Sun Chips
That’s the company’s way of letting the public know they are environmental and create their products using green energy. Their advertisement, like their product, is also made with the help of the sun, which sheds light on the billboard, reflecting the text.

It’s not often that you see billboards advertising potato chips, since they either don’t require advertising, or simply because they don’t know what’s the right approach to advertise this product. SunChips came up with the perfect way, which is not obvious and boring, but still obvious enough to make you wonder who’s in charge of their marketing.
