<p>A Caldecott classic celebrating twenty years in print.</P> David Wiesner received the 1991 Caldecott Medal for <I>Tuesday</I>. In the years that followed, he went on to receive two more Caldecotts, and <I>Tuesday </I>went on to sell half a million copies in the United States and to be published in a dozen foreign countries. Now, with remarkable advances in the technology of color reproduction, the original artwork for <I>Tuesday </I>is being reproduced anew, for an edition even more faithful to the palette and texture of David Wiesner's watercolor paintings. The whimsical account of a Tuesday when frogs were airborne on their lily pads will continue to enchant readers of all ages.
