Austria’s Leopold Museum made an offer to art lovers Saturday: Show up naked and you get in free. “Scores of naked or scantily clad people wandered the museum, lured by an offer of free entry to The Naked Truth, an exhibition of early 1900s erotic art, if they showed up wearing just a swimsuit – or nothing at all. With a midsummer heatwave sweeping Vienna, the normally reserved museum decided to make the most of its cool, climate-controlled space.”
