Oakland A's campaign San Francisco integrated creative agency, Hub Strategy, recently revealed new work for major league baseball team the Oakland A’s. It’s the third year of the well-received “Green Collar Baseball” campaign and the new design replaces the Athletic-tape-themed campaign of 2010 and 2011. Hub used bold color, typography, texture and, as “Chemistry” proves, a lighthearted approach to team dynamics. The campaign includes transit advertising, radio, TV and out-of-home.
