Tied on to a rosebush growing up a chainlink fence beside an enclosed wooden bulletin board for the Vinegar Hill community, Water St. (VH is just north of Dumbo on the waterfront in Brooklyn.)
Really surprised but happy this one's still hanging a full week later. It's a little abraded on the bottom corners, but otherwise in great shape. I don't think I've ever seen one still extant a full week later.
This location on Water St. in Dumbo is the block-long exterior of a majestic abandoned warehouse building, and a popular site for street art and graffiti. It's on the same block as Jacques Torres, Almondine, and St. Ann's Warehouse.
