Did you get it right?
Two modern medicine-package details slipped into this 1950s pharmacy shelf.

The Answer
The correct answer is: the child-resistant prescription cap and the blister-pack medication card.
Here is why
- One bottle has a ribbed child-resistant push-down cap.
- A foil-and-plastic blister pack sits among older paper boxes and glass bottles.
Why people miss it
Both items are small and medicine-related, so they feel natural until you compare them with the older packaging.
