McDonald's golden arches are one of the most famous symbols in the world – but did you know they were designed to subtly represent a pair of breasts.
The symbolism was devised in the early days of the burger restaurant that would become a fast food giant.
But McDonald's was ready to ditch the arches in the 1960s – when design consultant and psychologist Lewis Cheskin intervened and urged the company to keep the booby design.
The symbolism behind the golden arches was intended to represent a mother’s nurturing breasts - subconsciously making hungry customers feel comforted and at home, The Sun reports.
And the restaurant chain’s old slogan, “Give Mom a night off”, was also designed to fit this psychological pattern.
The golden arches went on to become one of the world's most powerful brand images.
Market research has found that children can recognise the company logo even before they learn to recognise their own name.
That makes McDonald's golden arches the mother of all marketing triumphs.
