"The first effect of looking at a good photograph through the stereoscope is a surprise such as no painting ever produced. The mind feels its way into the very depths of the picture. The scraggy branches of a tree in the foreground run out at us as if they would scratch our eyes out. The elbow of a figure stands forth as to make us almost uncomfortable." Oliver Wendell Holmes, an affordable stereo viewer inventor for the American market. Atlantic Monthly, June 1859.

Stereographs are devices capable of building a three-dimensional​ image out of two photographs that have about two and a half inches difference between them so that it could imitate the two eyes’ real field of view. Combining these images into a single one with the help of stereoscope, a person can experience the illusion of the image’s depth. Stereoscope uses the same principle as in human binocular vision. Our eyes are separated by about two inches, so we see everything from two different angles. When the brain combined those views in a single picture, we get the spatial depth and dimension. Stereographs were extremely popular between 1850 and 1930 all around the world. Millions of stereographs were made during that time. There was a broad range of themes: landscape, travel, historical moments, nature disasters, architecture and many others.

Pornography has existed for thousands of years and has taken many forms throughout history. In ancient civilizations, erotic art and literature were commonly produced and enjoyed, such as the Kama Sutra in ancient India or the sexually explicit artwork found in Pompeii. During the Victorian era in Europe, there was a significant rise in pornography as the advent of photography made it easier to produce and distribute. However, pornography was heavily censored and restricted during this time, and many erotic images were produced and consumed in secret. In the 20th century, pornography became more mainstream, and in the 1960s and 70s, the sexual revolution and the feminist movement helped to popularize pornography and change attitudes towards sexuality. During this time, retro erotic pornography became popular, featuring suggestive images and films that often had a vintage or nostalgic feel.
