Photo of the Day: 'You Done Great, Mr. Koch!'

Carroll Gardens businesses wore their heart on their billboards Friday, after hearing that former New York City mayor Ed Koch had died.

Outside of Peter Shelsky's store, Shelsky's Smoked Fish, a sandwich board had been handwritten with the message:

"You done great, Mr. Koch. RIP"

Meanwhile, other business owners said he was "more like mayor of the world." Follow the link for Carroll Gardens, Cobble Hill and Boerum Hill residents' reactions.
