The controversial "Nude Men" (NSFW) exhibit at Vienna's Leopold Museum is making headlines once again.

The collection, which covers (or, rather, uncovers) nude depictions of men in art "from 1800 to today," first attracted attention last year when X-rated street posters promoting the show were censored due to public outcry.

Two months later, the museum was once again in the news after a patron extemporaneously stripped down to his birthday suit and proceeded to experience the exhibit in the raw.

It was that incident which inspired a group of German nudists to request that the museum offer an after-hours showing for guests who wish to appreciate the nudes while nude.

The museum ultimately consented, and the event took place last night, with 60 "art lovers" — 59 men and a solitary woman — in attendance.

"Nude Men" has been a runaway hit with clothed visitors as well, attaching 100,000 people — the most ever for a single show at the Leopold.

Due to overwhelming demand, the exhibit's run has been extended through March 4th.

The museum is open daily from 10 AM to 6 PM. No shoes, no shirt, no pants, no problem.
