Every page contains two pictures that seem to identical but, in fact, contain a number of discrepancies (between 8 and 12). The number of discrepancies between the two pictures on each page is indicated at the top of the page.
Find the discrepancies, circling each one on the upper picture of each page.
After having found all of the discrepancies, you can color the pictures.
The solutions can be found on the back pages of the booklet.
