(click ad, via)
I don't know the agency. I don't know the year. I don't even know if it's real. And I don't care. I searched everywhere (well the three usual sources), and found nothing. I do appreciate any ad that doesn't show the product. At least they tried to be "creative". Here's two previous subtle WonderBra ads: one, two. And here's ten more WonderBra ads. Students: don't put spec WonderBra ads in your portfolio.
