A rectangular card box covered in dark blue paper that holds long slides. On the front of the box there is a label “4 Chromogrammes variés”. Inside the box there are 12 slides set in cardboard surrounds consisting of two identical shots sitting side by side on separate glass pieces. The whole slide and surround are approximately 13.5cm in length and 6cm in width. Some of the slides are attached by two short lengths of ribbon to either another slide depicting the same images, or a piece of cardboard that is slightly smaller than the one holding the glass images. It appears that the sets of slides depicting identical were originally meant to be conjoined into a single length of ribbon.
Each plain piece of cardboard is labelled with the image on some of the slides. There are four different images: a glass bottle, a portrait, a vase of flowers and some other flowers.
Accession Number: 2009.ph.131
Alternative Name: Chromogram Slides, Photographic Slides
Primary Materials: Cardboard, Ribbon, Glass, Paper
On a paper label affixed to a small face of the box: “4 Chromogrammes variés.”
On paper labels affixed to the cardboard slide covers: “C&G PARIS No.”
Dimensions (cm): Height = 5.5, length = 14, width = 7.5
These slides are intended for use with a chromoscope viewer, such as that developed by F.E. Ives (as in 2009.ph.130 or 2009.ph.22). Using such a viewer, these monochrome images are recombined through either a diffraction grating or coloured filters to created a coloured image.
Fair: the lid of the box is worn on the corners; originally it was connected to the base by a flap of paper but the glue holding it on has degraded and the lid is loose. The glass of the slides is intact, but the cardboard worn around the edges. The ribbons holdin the slides together into sets have broken.
