At Pick Me Up, Made North is showing a range of its projects, including beautiful limited edition A0 prints by Margaret Calvert, reproducing five of the most recognisable road signs she designed. Each design has been carefully refined by Calvert especially for this incarnation. This is typical of Calvert’s unstinting, career-long devotion to rigour in design, and an intelligent, humanist approach. When she designed the initial road sign symbols, the drawing of the cow in the ‘cattle’ warning sign was based on Patience, a cow on her relatives’ Warwickshire farm. And, eager to make the ‘school children crossing’ sign more accessible, she replaced the image of a boy in a school cap leading a little girl, with one of a girl (modelled on a photograph of herself as a child) leading a younger boy.
