This unique book studies haunted places, and the magic lens reveals 3 layers of hidden pictures.
Use the 3-color magic viewing lens to reveal a new view with each color—each page has three viewable images in one. Use the green lens to view famous landmarks, like Germany's Black Forest. The red lens reveals their rich histories. And the blue lens, if you dare use it, reveals the ghosts and ghouls that haunt the location. Spooky and educational fun.
