Keira models for Comic Relief T-shirts

One of the T-shirts features an image of her father, Sir Paul McCartney and his band mates taken at the height of The Beatles' fame.

Another shows Morecambe and Wise, the comic duo, captured by David Bailey, the veteran photographer.

One important addition has been made to the original photos, however; all their subjects have been given red noses.

Making it even more of a family affair, a host of celebrities and friends of the fashion designer, including Gwyneth Paltrow, Keira Knightley, Claudia Schiffer and Sam Taylor-Wood, have been photographed by her sister, Mary McCartney, wearing the T-shirts.

The T-shirts, priced from £5.99 for babies and children, and from £9.99 for adults, will go on sale on Monday at 214 TK Maxx stores nationwide, with all net profits from sales going to Comic Relief ahead of Red Nose Day on March 13.

Its charitable activities range from supporting orphans in Africa who have lost their parents to Aids or helping older people in the UK who are abused by someone they should be able to trust.

Miss McCartney said: "It's a real honor to be involved in such a tremendous cause and be a part of the Red Nose Day campaign 2009. The designs of the T-shirts were inspired by iconic images of iconic people by iconic photographers and adding an element of humour to them."

In line with her beliefs, the T-shirts are manufactured in Africa, using Fair trade-certified organic cotton co-operatives in Senegal, ensuring a pesticide and GM-free product at a fair price to farmers in developing countries.
