"I knew in a moment it must be St. Nick," wrote Clement Moore in 1822. Since then, his graphic Santa Claus image has become the world's. Moore's jolly old self, the reindeer-sleigh and chimney leap, the bag full of toys and visions of sugar plums so richly vivid in his poem, practically beg to be colored ? and now they can be, in this coloring book illustrated by John O'Brien. The text of the poem accompanies the drawings, most spread over two pages, which capture in marvelous detail that tingle of Christmas best sensed by children.
