"Keep calm and carry on" meets "running like a chicken with its head cut off" in the latest campaign from Adam&eveDDB and UK department store Harvey Nichols. The digital, print, and outdoor work predicts customers' frantic behavior during the store's summer sales, with headless chickens wearing bright colored Zegna, Valentino and MSGM-inspired pieces featured in the Harvey Nichols Spring/Summer 2013 collection. (The 'headless' theme follows up from the store's 2010 Headless Woman promotion). The sales begin next week and with prices beginning at 50% off, "try to stay calm" is probably good advice.
