Did you get it right?
The service-station office hides a valve cap, penny, pencil stub, and sailboat.

The Answer
The correct answer is: the valve cap, penny, pencil stub, and sailboat suggested by folded road maps.
Here is why
- The valve cap blends into the top fittings of the oil cans near center.
- The penny rests against the lower front edge of the desk.
- The pencil stub peeks from the rolled map near the lower center.
- The sailboat appears in the triangular map folds and broken desk shadow at lower left.
Why people miss it
The cans and map lines pull the eye across the whole desk. The sailboat is made from separate folds instead of one printed picture.
