The most famous shopping strips in the United States are unrecognisable as retailers board up their stores or block passing traffic entirely, bracing for election-related unrest in coming days.
Weeks out from unveiling its glittering holiday windows, Saks Fifth Avenue in Manhattan is a wall of plywood, joining the Disney Store in Times Square and chains including Macy's and Tiffany.
Businesses are hoping to avoid a repeat of looting and vandalism seen over the summer months following the death of George Floyd at the hands of police.
"While we intend to remain open where possible, out of an abundance of caution the windows of select stores in key cities will be boarded in anticipation of potential election-related activity," Tiffany spokesman Nathan Strauss told CNN.
The New York Times reports the "sea" of boarded buildings in NYC stretches from the high-end stores into the commercial districts of the Bronx and Brooklyn, reflecting a "broader national anxiety" as the US decides on Donald Trump or Joe Biden as President for the next four years.
According to Forbes, boarding up a storefront can cost between US$125 to US$31,000.

250 National Guardsmen have been put on standby, reporting to Metro Police officials.
The fence, which went up on Monday night, is similar to the barrier erected amid widespread protests after George Floyd was killed in May.
