Open any page of this oversized (14"x10") coloring book and you'll see an elaborate tangle of overlapping circles of various sizes. Teeny, tiny numbers - have glasses and/or a magnifier handy! - guide you to color the individual segments in five different shades...and eventually (astonishingly!) a famous masterpiece appears before your eyes! Big kids and adults alike will enjoy the twenty challenging color-by-number high-art puzzles. We don't know why they're called querkles, but we do know they're a whole lot of fun!
