Nude photography was widespread in France in the beginning of the 20th century. Postcards and stereoviews of nude models were readily available. The government tolerated these images as long as they were not obscene and did not disturb public order.
My first encounter with boudoir photos from the early 20th century was a coincidence. My purchase of a Taxiphote stereoscope included 74 glass stereoviews from Jules Richard's Atrium collection. I started reading about the history of erotic photography during La Belle Époque and discovered the photographs of Jean Agélou.
Jean Agélou was a French photographer who is known for his erotic photographs. His French postcards were very popular in the early 20th century, but he also created stereo photos.
