"As different as night and day," goes the old saying, and this elegant book takes prereaders through a series of opposites of all kinds, from large to small (and tiny), long and short, front and behind, above, below, open, closed, together and alone. Colorful pop-ups, lift-the-flaps, and cut-outs—a bit reminiscent of Alexander Calder or Joan Miro's art—create an interactive sharing experience that is both lively and instructive, with opportunities to introduce the names of colors, shapes, and animals.
