The marketing hook behind Calendar Girl may just be the main example for those critical of London's musical career, since its sleeve has made it a prized collector's item. The famous wraparound cover depicts cheesecake shots of London posed for every month of the year, while original issues of the album included a more-than-suggestive insert photo of the singer stretched out in bed.
