Did you get it right?
This 1970s campground registration desk shows a paper map, lantern, cabin keys, postcard rack, coffee thermos, and office clutter. Two small details are from a later time.

The Answer
The correct answer is: The two mistakes are the modern tear-resistant plastic wristband and the peel-off cooler-label strip..
Here is why
- The lantern, paper map, cabin keys, postcards, and thermos fit the campground setting.
- Check the map area and the postcard/cooler-label area closely.
- The wristband and peel-off label strip are modern material clues that would not belong on that desk.
Why people miss it
Both mistakes are small and color-matched, so they read as ordinary campground paperwork until you notice the material and shape.
