People like to rag on advertising, but as Jumbtotrons have shown, they lose their minds when they see themselves on a billboard. Robbins Brothers, a jeweler out in California, has come up with the Facebook version of this. Type a love note to someone on the brand's Facebook page, and they'll upload it to a digital billboard on the 91 freeway in Riverside, Calif. Then they'll take a photo of it and send it to you, so you can share it with your loved one. G&M Plumbing (one of our 40 mostly oddly named agencies, by the way) worked with Rey Interactive on the social-meets-out-of-home campaign. The TV component is also sort of fun, featuring YouTube videos of actual proposals set to Colbie Caillat's "I Do."
