Models Elizabeth Hurley and Jasmine Guinness have donated family photos to be used on a new set of stamps to raise money for domestic violence charity Women's Aid.
Hurley contributed to the cause with a picture of her six-year-old son Damien, reports dailymail.co.uk.
"The images I have chosen mean a lot to me as a mother and it is great that my photography can be used in a way that benefits others," she said.
Said a Royal Mail spokesman: "This is the third year we have run this auction, having worked with Helena Christensen and Penny Lancaster in past years to raise considerable funds for Women's Aid."
"It has proved to be so popular that we invited Elizabeth and Jasmine to come on board for 2009 and are keen to raise as much money as possible for these worthwhile causes."
The limited edition stamps will be sold on auction website eBay and the 10-day auction begins Wednesday.
