4. Kentile Floors

The Kentile Floors sign is so famous that it has its very own Facebook page. Although it was taken down in 2014, the 50-year-old icon was fortunately saved and donated to the Gowanus Alliance, which will reinstall it in a nearby location.
Used to advertise a now-defunct flooring company founded by Arthur Kennedy in 1898, the sign paid homage to Brooklyn’s industrial heritage, and long served as a symbol of Gowanus. According to Curbed NY, the alliance plans to erect the sign at Gowanus’ Under the Tracks playground, located on 10th Street between Second and Third avenues.
