Édition or Éditions Paris-Stéréo was a trademark of Albert Baron. Baron was first mentioned as a photographer and publisher in 19101. In 1922, his company was located at 55, Boulevard Lefebvre in Paris2. The trademark Paris-Stéréo was probably introduced by Baron in the early 1920s. Baron advertised with and without the Paris-Stéréo name over the years, leaving the exact introduction of the brandname unclear.
Baron’s stereoviews were sold in series of 12. The series shows sights from France, Algeria, Italy and Belgium. This specific and limited list of countries, and the fact that Baron was listed as a photographer, suggest that the images were photographed by Baron himself.
A small range of glass stereoviews exist, but Baron was mainly known for its paper card stereoviews in the 8.5 x 17 cm format. Series with scenes from the First World War were published during and after the war.

War Stereoviews
Paper card stereoviews
A catalogue with the title Vues de la Guerre lists ten series of 12 stereoviews in the 8.5 x 17 cm format with war scenes. The catalogue does not mention the name of Baron or Paris-Stéréo. The stereoviews have a number in the 25xx to 28xx range. Most series are not dedicated to a specific theme or battle. The catalogue and series were published during the war and subject to censorship.
In a later catalogue the number of series is extended to 20. The series from the first catalogue are listed, with some stereoviews replaced with other numbers, and ten new series were added. The numbers run to 29xx. This time the catalogues mentions the name Paris-Stéréo, and this reference links the first un-named catalogue to Baron and Paris-Stéréo. This later catalogue mentions that the views are authorised, so this catalogue and series were also published when censorship was active.
The number sequence of the stereoviews in the catalogues is not consecutive and shows gaps. Remarkably, non of the series contain images of the Battle of Verdun. Taking into account that some images were swapped with new ones, the total number of 8.5 x 17 cm images is estimated 300.
Glass stereoviews
Baron also sold glass stereoviews in the 6 x 13 cm and 45 x 107 mm format, but the glass slides are far more rare compared to the 8.5 x 17 cm stereo cards. The images of the 6 x 13 cm glass stereoviews were also printed and published as 6 x 13 cm paper card stereoviews. The 45 x 107 mm slides were cropped versions of a 6 x 13 cm image.
The glass slides also have numbers in the 25xx range and higher. The previous mentioned gaps in the 8.5 x 17 cm series are actually 6 x 13 cm slides. So each war stereoview, in each format, was given a unique number by Baron. There might have been a separate catalogue for the 6 x 13 cm series. The total amount of 6 x 13 cm stereoviews is unknown.
Vues de France
Baron introduced new series with the title Vues de France after the war. These series contain images of France and include some series that are related to the war. The 8.5 x 17 cm paper card stereoviews have a different presentation and numbering scheme compared to Baron’s earlier views. All cards show the name Paris-Stéréo and Vues de France.
