The last bastion? Artist Elizabeth James of Australia paints New York Harbor from Governors Island with the Manhattan skyline behind.
Manhattan's most famous parks are lined with artists selling their sculptures, paintings and photographs — often of quintessential New York scenes — but city officials say the vendors have grown out of control and are trying to force many of them off the streets.
Mayor Michael Bloomberg's administration wants to shrink the vendor population by up to 80 percent in some areas — dramatically altering a colorful part of the cityscape that has for decades served as an outdoor gallery popular among tourists in a city known worldwide for its arts.
"If they do this, it will be war in the city because so many people will lose money and a place to show their work," said Alex Basansky, a photographer who sells his prints of city scenes at the southeast entrance of Central Park.
The regulations would also severely limit the number of vendors in parts of Central Park, plus all of Union Square and Battery Park in downtown Manhattan and the High Line Park, a new elevated park along Manhattan's far West Side.
Painter Robert Lederman, President of A.R.T.I.S.T (Artists' Response To Illegal State Tactics), told NBCNewYork that his some 2,000 members will fight the new rules if they pass.
"We will resist, we will be arrested, and we will sue," said Lederman, who believes the new laws are unconstitutional.
Lederman said hundreds of ARTIST members and their supporters will protest a hearing on the issue next Friday.
"We have the exact same right to sell in the park as you do to walk into a park and interview somebody," said Lederman, who has been arrested twice for selling art in the High Line park. All charges have been dismissed.
He says that the city is just looking for the same kind of money that it gets from food vendors who pay hundreds of thousands of dollars a year for the right to sell in the parks.
But as Union Square vendor/artist Kunga Norbu put it thusly: "The hot dog vendor doesn't make his hot dog. We make art we are artists."
Lederman said pushing out poor artists would change the character of the Big Apple.
"First of all it would immediately displace about 400 artists that are in the parks, and those artists aren't going to go out and get a job on Wall Street -- It's going to cause a huge additional number of street artists on streets that are already crowded," he said. "And it's going to greatly diminish the cultural diversity of the city."
Ryan Merryweather, who sells "mobiles with a postive message" like "adorable," "brave" and "enjoy," in Union Square echoed Lederman's sentiments.
"They're trying privatize the park," said Merryweather. "I think they're trying to make the whole of New York boring. Get rid of the artists."
The Bloomberg administration says street art has outgrown its space in the city's most popular parks, dominating sidewalks and interfering with pedestrian traffic. Vendors say the rules violate their First Amendment guarantee of free expression.
"It's about balance," said Parks Commissioner Adrian Benepe. "They can still vend their stuff, they just can't do it in uncontrolled droves where park visitors are forced to walk through a gauntlet of vendors."
Vendors currently do not need city permits to sell what is called "expressive art," which includes writings and visual art like photographs, paintings and sculpture.
Officials say there are now more than 300 vendors in the four most busy parks, and seek to cut it down to 81.
The Parks Department is holding a hearing next week on the regulations. If the rules are passed, vendors say they will challenge them in federal court.
Renowned First Amendment attorney Martin Garbus, who has no connection to the case, said the artists likely have a good argument. He said the city would have to prove that vendors create a serious problem, like blocking a critical intersection, for example.
"You can't regulate them if all they do is sell peacefully," Garbus said.
In anticipation of the fight, vendors in the parks are displaying yellow signs saying "Stop Harassing the Artists" and "Artist Power."
One artist in Union Square created a mock old-West style poster, with a photo of Bloomberg, that read "Wanted: Killer of NYC Artists' Rights."
Under the regulations, 18 vendors would be allowed in Union Square. On a recent sunny weekday morning, more than 50 vendors had set up tables by 11 a.m.; on weekends, the number can reach 100.
The city says the relatively small park can get 200,000 visitors per day during the summer season.
"I'm very concerned — we're being driven out," said Ava Day, an oil painter who sells her landscapes for $10 to $25 at a table along 14th Street, the park's southern border.
The rules for Central Park would allow a total of 49 vendors — nearly half of them in front of the Metropolitan Museum of Art, and the others between Columbus Circle and Fifth Avenue on the park's south side. Officials say those areas combined typically have 100 to 150 vendors.
In Battery Park, where tourists line up to take a ferry to the Statue of Liberty, nine would be allowed — down from about 50 — and five on the High Line.
Twenty-five million people visit Central Park a year; Battery Park gets 4 million visitors annually. The High Line just opened last year.
The rules for all the affected parks say vendors would get the designated slots on a first-come, first-serve basis.
"It's whoever gets there first, and this is going to lead to people sleeping there, people fighting for spots," said Joel Kaye, a New York University professor who sells his art — photographs of mostly city scenes printed onto tiles — three days a week in Union Square.
The city has unsuccessfully sought to limit art vendors on the streets in the past.
In 1996, when Rudy Giuliani's administration sought to require permits for sidewalk artists, a federal appeals court sided with the artists and said they were protected by the First Amendment. The U.S. Supreme Court declined to hear the city's appeal.
It wasn't clear that the city's concerns about overcrowding were a concern to tourists.
As vendors began to set up tables Friday morning in Battery Park, Patricia Glyn of Johannesburg, South Africa, said she didn't think they were in the way and that people have the right to try and earn a living.
"It's probably good to have as many as possible," Glyn said, "as long as they aren't aggressive and don't block the walkway."
The public hearing will be held on April 23, 2010 at Chelsea Recreation Center, 430 West 25th Street in Manhattan, at 11:00 a.m.
