The uniquely informative and charming art from Rachel Ignotofsky's book The Wondrous Workings of Planet Earth portrays our planet in this family-friendly 500-piece puzzle. As you piece the puzzle together, you'll tour our planet's incredible ecosystems large and small, from reefs, deserts, and rainforests to ponds, backyard gardens, and even a drop of water. A poster that features the puzzle design on the front is enclosed to reference while assembling the 18 x 24" puzzle.
