The phantom hand
Even catalogs made by professional designers have their flaws. They’re usually minor, like photoshop mistakes and discoloration, but sometimes, you’ll come across some pretty strange slip-ups. Take a look at this picture and try to find the phantom hand.

There it is, wrapped around the mother’s shoulder. It can’t be the father’s right hand since it’s dangling at his side. It’s possible that it’s the son’s right hand, but he’d have to have a really long arm that bends at awkward angles. This is one of those mistakes that most people wouldn’t notice unless they have nothing better to do.
