Did you get it right?
This dry-cleaner counter shows claim tickets, wire hangers, garment bags, a chalkboard price list, a wooden counter bell, and an old shop counter. Two small details do not fit the period.

The Answer
The correct answer is: The two mistakes are the modern plastic garment-tag fastener and the heat-transfer care-label corner..
Here is why
- The paper claim tickets, hangers, garment bags, and counter bell all fit the old dry-cleaner setting.
- Look closely around the paper tags and the edge of the garment bag.
- The plastic fastener and heat-transfer label are newer clothing-care details.
Why people miss it
Dry-cleaner counters already have many tags, clips, and labels, so the modern materials blend into the normal pickup routine.
