Did you get it right?
Compare panels A and B around the county-fair sign, bunting, prize ribbons, three pies, score cards, and checkered tablecloth.

The Answer
The correct answer is: There are five visible changes in the county-fair pie-contest scene..
Here is why
- Difference 1: One bunting flag near the top changes color.
- Difference 2: The first-place ribbon has a different lower-tail detail.
- Difference 3: The second-place ribbon tails are shaped differently.
- Difference 4: The vent on the middle pie changes from a star to a cross.
- Difference 5: The middle score card changes from 8 to 7.
Why people miss it
The large sign and bright pies pull attention away from the small ribbon and bunting changes. The score card is obvious only after a slower second pass.
