When John Richard Baker, Assistant National Park Officer for the Yorkshire Dales, died in July 1998 from leukemia, his wife Annie and her best friend Chris got the ladies of the local Women’s Institute together with the idea of producing a calendar to raise money for cancer charity. Each month would feature a different woman in the women's group, doing ordinary things like making jam, flower arranging, or knitting. The traditional idea had a radical twist -- the women would appear nude. The calendar gained international attention which eventually led to the filming of the Calendar Girls movie.

When Baker was diagnosed with cancer, he began growing sunflowers and gave them to friends and family --hoping to live long enough to see them fully-bloomed. Unfortunately, he lost his life to cancer before that happened. The sunflower has become the cancer charity fundraising activities symbol for his family and friends.

Wearing bras decorated in sunflowers, the Calendar Girls, together with friends and family, are now training for London's Playtex Moonwalk, a cancer charity fundraising event in which thousands of women walk 26.2 miles through the night wearing elaborately decorated bras.  While the past efforts of the women's group have raised more than £1m total for leukemia research, this walk will be for breast cancer charity. In addition, the Calendar Girls recently launched a 2007 calendar. Profits from the calendar will continue to go to leukemia research.
