Did you get it right?
This family den game table shows checkers, a score pad, snack bowl, soda bottles, magazine, and wooden tray. Two details are from a later era.

The Answer
The correct answer is: The resealable snack-bag zipper strip and the molded plastic game-piece storage clip are the two mistakes..
Here is why
- The checkers, score pad, glass bottles, magazine, and den setting fit the 1970s.
- Check around the snack bowl and the game-piece area.
- The zipper strip and molded storage clip are modern packaging and storage details.
Why people miss it
Game tables always have little pieces, wrappers, pencils, and snacks, so modern items can hide as ordinary clutter.
