Hello Goodbye: The Magic of Opposites
Hello Goodbye wittily presents pairs of words such as light and heavy, night and day, and near and far in amusing illustrations that come to life, one word at a time,
thanks to an included viewer with two filters —a red one and a blue one —that is very easy to use. The red filter makes the red illustration disappear and the blue appear,
and vice versa. The interactive quality of the book catches children’s attention and encourages them to make connections with words they are familiar with —all while keeping them entertained.
