Did you get it right?
Two modern grooming details slipped into this 1960s barbershop.

The Answer
The correct answer is: the multi-blade plastic razor cartridge and the molded pump on the tonic bottle.
Here is why
- The razor standing near the right side has a modern snap-on multi-blade cartridge.
- The green hair-tonic bottle at far right uses a molded plastic pump dispenser.
Why people miss it
Both objects sit among familiar glass bottles, porcelain fixtures, and metal tools, so their modern fittings initially seem natural.
