It's been over a year since the Kentile Floors sign graced the air space above the Gowanus Expressway. The sign is now under the stewardship of the Gowanus Alliance, who are looking after it (and giving it photo ops) until its reconstructed at a yet-to-be-named location—we hope.

Eagle Clothes, initially purveyors of fine men's clothing, opened their Gowanus plant in 1951. The brand felt the kiss of death with the rise of the men's leisure suit in the 1970s, ForgottenNY explains. The company filed for bankruptcy in 1989, and the sign was eventually removed by U-Haul who owns the building it sat atop of for more than 60 years. [Image via Citynoise]

Okay, so this is less a “sign” and more a building; but the meticulous, beautiful pieces of graffiti that adorned the Long Island City warehouse until its 2014 demolition were so iconic (even as they changed regularly) that they deserve a spot on this list. Particularly notable was the tag containing the building's insignia, which you can watch crumble over and over again here.

Speaking of much-missed St. Marks Place businesses, this all-night diner was known for its enormous portions that helped remedy the after-effects of a long night out, and the huge sign that was painted on an adjoining building. The restaurant closed in 2014, and when it becomes a Portuguese restaurant (the current plans for the site), the sign will be gone, too.

The beloved punk-rock shop has occupied a 19th-century townhouse (once owned by a Hamilton!) on St. Marks Place for 40 years, but with the sale of the building comes the inevitable ousting of Trash & Vaudeville. The shop will be moving, but St. Marks just won’t be the same without the iconic neon sign that marked the store’s entrance. [Image via New York Neon]

Just one of the many things in New York that seeped mysterious steam, the Times Square Cup Noodles sign stood prominently on its perch at 1 Times Square, behind the New Year's Eve Ball, from 1996 through 2006. [Image via Wikimedia]

A decade after the CNN sign went up on 1775 Broadway (which has since be renamed to 3 Columbus Circle), it’s now gone. The building’s landlord, SL Green, replaced it with an LED sign that displays the time and weather, along with the firm’s logo. CNN, meanwhile, will move its HQ to Hudson Yards in a few years.
