A PLACARD tied to a cow neatly summed up the message at this demonstration.

Farmers staged a demonstration at Bicester in 1970 to press home their argument that while the price customers paid for a pint of milk went up by 31 per cent between 1954 and 1969, the price they received had risen by only 11-and-a-half per cent.

Agnes Salter, pictured talking to one of the policemen on duty, was in charge of making sure the cow observed the rules of peaceful protest.
