From inside the app itself.
Love simple old-timey ads like this. Very likely hand-lettered, giving it that garage-sale sign look, like how when people having to squeeze letters because they didn't visually plan for the space before they started writing (compare "every" to "whiskey").
Do both sections, the "What?" section has fantastic scrolling effects and the survey is an experience to behold.
I'm a sucker for text that knocks out photos.
Fun, romantic, surprising, beautiful.
