Graffiti artist and prankster Banksy opened his first Los Angeles show on Friday in an obscure warehouse in industrial Downtown, bringing his subversive humour and anti-capitalist message to a city better known for wealth and self-obsession.

Barely Legal, a free three-day event billed as a "vandalized warehouse extravaganza," opened with the excitement and puzzlement that has come to be the hallmark of the elusive "guerrilla artist".

Banksy keeps his identity secret but has built up a cult following in Europe over the last four years, placing his work in top museums, zoos or on the streets.

"It is really amazing. I think he is hilarious," said Los Angeles graphic designer Manny Skiles, 30, who has spent two years following Banksy's work mostly through the internet.

Skiles and dozens of others spent more than an hour lining up to buy $US500 limited print editions of Banksy's work. The originals sell for up to £25,000.

On one wall, a stencil art picture shows bush hunters in loincloths raising their spears at empty supermarket shopping carts. On another, a masked street anarchist with a thrown back arm prepares to hurl - a bunch of flowers.

But the placid pink elephant takes pride of place. Tai, 38, looms large in a room decked out with a sofa, a television, rugs on the floor and a man and woman sitting reading obliviously on the couch. It is titled Home Sweet Home.

"We are sitting on the couch not seeing her. From what I understand, the elephant is a symbol of all the world's problems being ignored," said Kari Johnson, Tai's caretaker. Johnson said Tai lives on a private southern California elephant ranch and has appeared in several commercials.

Banksy, as is his custom, was not around to discuss his show, which followed a prank at Disneyland this month in which he placed a blow-up figure dressed in orange Guantanamo Bay prison overalls beside a roller-coaster ride.

Last month, Banksy placed remixed copies of Paris Hilton's debut CD in stores across England. He gave them titles such as Why Am I Famous? and What Am I For?

In the Barely Legal show, the fake Hilton CDs are displayed in a plexiglass case alongside photo-shopped pictures of the hotel heiress and live cockroaches.
