Ferrier & Soulier was a major publisher of exclusive glass stereoviews in the 1850s and 1860s. Most of their inventory was based on their own stereo photos, but they also published stereoviews from the glass negatives of other photographers. The enormous popularity of Francis Frith's photographs of Egypt prompted the company to purchase a series of negatives in 1859.
Francis Frith's stereo photos had already been published by Negretti and Zambra in England. This publisher also sold the stereoviews of Claude-Marie Ferrier and this connection probably allowed Ferrier & Soulier to purchase the negatives of Frith's stereo photos.
The glass stereoviews of Egypt by Ferrier & Soulier were presented in the same way as Negretti and Zambra had done. The slides have a size of 8,5 x 17cm and consist of two glass layers. The glass plate with the albumen print is covered by a glass plate that's painted on the inside with a black passe-partout of wide, flat-arched, double windows with single gold fillets. The back contains a paper strip with the number, title and a description of the image, translated into French from the original English text. The original stereoviews by Negretti and Zambra were numbered 300 to 399. Ferrier & Soulier added the prefix 2, so the stereoview with number 368 appears in the Ferrier & Soulier catalog as 2368. Francis Frith scratched his name and a number on his negatives and on some of the Ferrier & Soulier slides the original number is still visible.
Ferrier & Soulier created a new way to produce labels with descriptions in 1859. They were printed on thin, transparent, gelatine sheets in black ink and attached to a cleaned area on the emulsion side of the glass slide. The paper strips with descriptions on the back were no longer used.
