How to See a Hidden Picture in Stereogram?

What is a Stereogram picture? It is a three-dimensional image created from two-dimensional images. Stereogram was invented by Charles Wheatstone in 1838. There are two famous ways to view a Stereogram image. In fact to view this image one has to see beyond the boundaries of two dimensional given image. In both these methods, we try to see beyond the surface, and then the 3D image appears. Below are two methods for looking at these pictures

1. In the first method start by keeping the image very near to your eyes with your nose touching the surfaces. Try to concentrate on the center of the image and slowly move the surface away from your nose. After you move this image at a certain distance, you will be able to see the 3D Stereogram image.

2. The second method: Put the semitransparent sheet on the surface. You will see your reflection in this sheet as well as the given 2D image. Do concentrate on your reflection. It is equivalent to looking beyond the surface. After some time your reflection will disappear and you will see this 3D image.

For some people, it takes time to see the image for the first time. However, be patient and keep trying. If you are able to see this image, then it becomes very easy to see this image again. I mean all these efforts are to see the 3D hidden image only once. After you are successfully looking once, then your eyes and brain will immediately focus to see the image when you look at it next time.

Here I am posting one Stereogram picture below. If you have never seen any Stereogram picture earlier then it's challenging for you to find the hidden picture in this image?
