Prince William will soon find a calendar of several naked women in his mailbox but he should not get worried as these women have stripped for a noble cause. A group of 14 British women, aged 19 to 50 years, have shed off their clothes in a bid to raise cash for East Anglian Air Ambulance, where Prince William is a pilot. The women now plan to send him their "Country Ladies Uncovered" calender.

The women have showed off their bodies in various backdrops and have made a calendar for all the t12 months. In one picture, the women can be seen chopping woods wearing shorts while the other shot sees them hugging each other along the trees. Yet another shot shows them dressed only in panties and sitting in a room with a piano. There is also a solo picture of a naked woman riding a tractor.

Titled "Country Ladies Uncovered," the calendar aims to raise charity for the East Anglian Air Ambulance, a service which is of utmost importance in the countryside. The pictures have been exclusive shot by Julie Ayres, who too is a country woman.

"I've wanted to make a calendar for a long time and I'm country born and bred and know lots of equine ladies so it seemed a good theme," said photographer Julie Ayres, according to Daily Mail.

"Most of us live in the countryside and ride and we know it's likely we may have to call on the air ambulance at some time. I have seen the pilots land in some very precarious places and I'm in awe of them, so we wanted to do something to help the charity," she added.

The photographer told the website that she admires the girls for their courage and the cause they have taken up. Julie also reveals that it was in fact quite easy for her to shoot the pictures of women once they got comfortable with each other. However, the "hardest part" for her was to decide which woman will show which part of body in the photo shoot.

Prince William is currently undergoing training with the East Anglian Air Ambulance charity for his helicopter air transport pilot's license. The service provides emergency medicine at the scene of accidents and have a team of clinicians. In 2013, the charity was responsible for flying close to 1500 missions and reportedly reached out to more than 1,000 patients involved in various accidents, according to the website.
