This collection of heart imagery highlights how a universal symbol can be creatively interpreted and constantly reinvented. It captures the breadth of art and design imagery exploring the meaning and representation of hearts. Although the focus is on the contemporary, it also touches on the history of the symbol from the Sacred Heart cult to the invention of the Valentine, from heart tattoos to pictograms. The Book of Hearts is an exploration of the meaning and representation of love and emotion through one of the most recognisable signs in the world.
