This year's nipple-studded Pirelli calendar, being printed in a limited run of 35,000, is a prime candidate for auctioning by the lucky few who've gotten their hands on one (we hear it's mostly staff, who get one each). There are already a bunch listed on eBay, bid to or buy-it-now priced from 100 to 300 tin farthings (or whatever our British friends use for currency these days), that's between $175 and $525. Some rumorists say it's the last one, thus the enthusiasm. That and the pics of J-Lo in a Leather Daddy cap.
