"Sainsbury's: The House that Helps you to Economise!" advert proof for Crelos Margarine

There is a black pen and ink style illustration of Sainsbury's Head Offices with an illustration of a giant chef leaning on the building. Then within a border beneath it the headline is - Sainsbury's, underneath are the words The House that Helps you to Economise! No finer Economy than 'Crelos' Margarine. Dr. Joseph, Medical Officer of Health for Warrington, says: "Margarine contains as much food-value as best butter". The Grocer's Gazette says: "The difference in price between margarine and Butter simply represents what the consumer is willing to pay for luxury".
