Hundreds of people stripped off - but most kept at least something on
A prestigious Vienna art gallery has encouraged art-lovers to strip off, letting naked or scantily-clad visitors in for free.
The Leopold Museum hosted hundreds of skin-baring sightseers to mark the launch of The Naked Truth, an exhibition of early 1900s erotic art.
"We find a naked body every bit as beautiful as a clothed one," museum founder Elisabeth Leopold said.
The exhibition in the Austrian capital hosts artworks by Klimt and Schiele.
The gallery's commercial director, Peter Weinhaeupl, said he wanted to help people cool off in heat that hit the mid-30s Celsius (mid-90s Fahrenheit).
He also said he hoped to create a mini-scandal reminiscent of the shock when the artists first unveiled their risque paintings.
"It's a bit of an experiment," he said. "Egon Schiele was a young and wild person in his day. He'd want to be here."
The 180 works will be on display until the end of August
Mrs Leopold, who set up the museum with husband Rudolf, added: "If they came only out of lust, we have to accept that. We stand for the truth."
One visitor, Mario Vorhemes, 20, wore just a pair of swimming briefs and asked: "What's the big deal?
"We're born naked into this world. Why can't we walk around in it without clothes from time to time?"
