MAY I ask readers going on holiday here and abroad to add another postcard to their list and send it to Dr Hadwen Trust c/o 18, Fletton Avenue, Peterborough, PE2 8AU.

These will be auctioned to raise funds for research into cancer, diabetes, heart disease, meningitis and Alzheimers. Also needed are foreign stamps, preferably still on the envelope, first day covers, British stamps, phone cards, old and foreign company, clear postmarks and of course picture postcards. Anyone wanting to know about this work that relates directly to humans and is safer, cheaper and more reliable than animal research, write to Dr Hadwin Trust, 84a Tilehouse Street, Hitchen, Herts.

Dorothy Benton, Fletton Avenue, Peterborough.
