Has Anyone Seen Jack? by Tony Bradman
Jack's family is very poor. They send him to sell Daisy the cow but he foolishly swaps her for a magic bean and then has to hide from his mother who is furious. He makes his way up the beanstalk, but then has to hide from the boy-eating giant who lives at the top. Lift the flaps to discover Jack's hiding places and how he saves his family from rack and ruin.
