Optical Illusion: Only a sharp-eyed person can find the ladder in this picture

For today's optical illusion, we'll be assisting a cute child in reaching several books. Confused? Take a look at the photo below. The illustration depicts a library full of books and some children who enjoy reading them. However, the majority of the volumes are stored on high shelves. For this illusion, you will assist a young child in reaching one of the books stored on the top shelf.Fortunately, there is a ladder that she can use. However, the ladder is nowhere to be discovered. So now your mission is to locate the ladder kept in the library.
Only persons with strong eyesight and quick observation abilities will be able to locate the ladder in under 10 seconds; the rest may take longer.
Optical illusions and puzzles are excellent techniques to improve brain skills such as observation and problem-solving. They also help to improve one's mental focus. Aside from these, exams such as IQ tests and personality tests can help individuals learn more about their IQ level and personality qualities.
With that said, let us begin the timer for the optical illusion:
One, two, three, four, five, six, seven, eight, nine, and 10... And your time is up!
Have you spotted the ladder yet? Or do you need some hints? For hints, glance at the shelves; maybe you'll find anything there.
Do you see the ladder now? Great work!
