|Let's call this ?A? for ?Andetta.? Yes, that's a huge portion of the Cushman & Wakefield brokers in Atlanta wearing Andy Ghertner masks (well, except for the actual Andy in the middle front there). The tribute was performed during a company retreat at Burge Plantation earlier this month. The firm celebrated Andy's 35th anniversary at C&W. Known as the ?dean of Atlanta real estate,? his firm surprised him with the masks.
