'City Acrobat', a narrative pop up book, is about life in the big city. The main character, an isolated female acrobat, represents the self portrait of a citizen. She needs to perform on the high wire all day, like the workers labouring in the city. Infinite roads, crowded buses, and skyscrapers illustrate the routine life of the busy citizen. Like the female acrobat's dream, the city we belong to might not be the real world, but a kind of stage that we need to perform on.
