When I came across this book, Incredible Visual Illusions: You Won’t Believe Your Eyes! I was elated as I thought, “Oh boy, a new book of Optical Illusions by Al Seckel. When I got home I checked my library and found I already had it but it didn’t have the same cover. My copy is identical in every way, same chapters, every page the same and also 256 pages. It was published in 2007 but on the cover is “Visions of Don Quixote” from page 159 the “Rubik’s Cube” from page 72;”Kitaoka’s Spinning Wheel Illusion” from page 107 and “The Ames Room from page 250. It may not be an Optical Illusion but certainly proves the old adage. “You can’t tell a book by its cover.” BUYER BEWARES! You can purchase this book at Puzzle Master.
