Take a quantum leap into the bizarre and extraordinary parallel worlds presented to you in this Spot the Difference puzzle book, showcasing the surreal collage art style of Louis Catlett.

This intensely visual puzzle book is filled with over 40 mind-boggling, full-colour picture puzzles, where nothing is quite as it seems... Focus on the absurd, trippy and psychedelic situations presented in the pairs of images and see if you can spot all the differences between the two.

Was that rubber duck always pink? Did that chimp always have a jetpack? Where did that sinister floating hand disappear to? Take a closer look and the intriguing inconsistencies will reveal themselves...

This hilarious puzzle collection makes a unique gift for any puzzle fan!
