Did you get it right?
Two small modern details are hiding among the robes, hymn folders, garment bags, and shoes.

The Answer
The correct answer is: The mistakes are the molded plastic zipper pull and the peel-away backing on the name badge..
Here is why
- The modern zipper pull is on the clear garment bag at center right.
- The Eleanor badge on the front-left robe has a curled adhesive backing corner.
- The rest of the closet uses older cloth, paper, wood, and metal details.
Why people miss it
