Stereoscope ‚Celdé‘, with roll film set

At around the same time as the Stéréo-Plas­tique Alain, cir­ca 1950, anoth­er pub­lish­ing house, Édi­tions d’Art Celdé, whose address was in Lour­des at 52 rue du Bourg, appeared. Like Roland Barnier, this pub­lish­er offered post­cards and stereo­scop­ic film strips in the 45x107mm for­mat, pro­duced on pos­i­tive Kodak film and depict­ing sim­i­lar sub­jects. One can also note the sim­i­lar­i­ty of the pack­ag­ing and the com­pat­i­bil­i­ty of the films, which can be viewed in both stere­o­scopes despite the dif­fer­ent designs of the two view­ers. The Celdé stere­o­scope is made of card­board cov­ered with paper. This rais­es a ques­tion: were the two com­pa­nies part of the same busi­ness, or were they linked by a com­mer­cial agreement?
The stere­o­scope pro­duced by Édi­tions Celdé appears to have been based on a patent by Paul Syl­vain Sabathi­er of Toulouse, who filed his French patent FR 1.041.869 on 14 August 1951 for a stereo­scop­ic appa­ra­tus using film with trans­verse move­ment. The patent incor­po­rates the use of card­board con­struc­tion, focus­ing by means of a slid­ing draw­er with an adjust­ment at the rear, and a mech­a­nism for ver­ti­cal­ly advanc­ing the flex­i­ble stereo­scop­ic film — the same for­mat used by Édi­tions Celdé.
