Unidentified photographer / artist 1924 The Taxiphote was an instrument designed for viewing and storing both black and white and autochrome stereoscopic transparencies.
Please note that the date given here of 1924 relates to the printed catalogue rather than to the invention of the Taxiphote that came out in around 1900 for black and white plates. One of the stereo autochrome formats (45mm x 107mm) was the same as that used by the Taxiphote and therefore it could be used for them.
