Did you get it right?
The two bookmobile panels contain five visible differences.

The Answer
The correct answer is: five changes involving the bus number, sign tassel, book colors, and bird position.
Here is why
- The bookmobile number changes from 27 in panel A to 32 in panel B.
- The hanging tassel beside the book sign changes from blue to red.
- The book being handed out changes from red in panel A to blue in panel B.
- The top book in the child’s stack also changes from red to blue.
- The bird moves from the grass near the tree to the back of the bench.
Why people miss it
The people and bookmobile stay very similar, so the eye has to check small color and position details.
