Cartoon characters who cheer up young patients in Oxfordshire's hospitals will be wishing people a Merry Christmas on greetings cards this year.

Dr Rad and Nurse Cliffe were brought to life two years ago to entertain children being treated at the John Radcliffe Hospital, in Headington, Oxford.

The pair have become so popular that they are starring in Christmas cards which will help raise money for the JR, as well as Oxford's Churchill Hospital and Radcliffe Infirmary, and The Horton, Banbury.

Fundraising manager Janet Sprake said: "Since we came up with the characters we have used them on anything that is associated with children's services.

"We've done Christmas cards for the last few years, but they've always been quite traditional designs. So this year we decided to use Dr Rad and Nurse Cliffe. So far we've had a good response."

Oxford University Press graphic designer John Taylor, who devised the characters, said: "I was asked to design Christmas pictures, so I just racked my brains for ideas that were hospital related. I'm glad that they are doing the trick for patients."
