Glass slides for the Multiple Image Projector (2009.ph.117), contained inside a wooden box. The box has a hinged lid with two rotating hook latches to hold it closed. Inside the case, there are 15 glass slides which are approximately 12.5cm x 10cm in dimension.

Tucked into the interior of the lid of the box there is a piece of cardboard which describes the content of each slide.
Each slide is rectangular and is opaque due to a layer of paint or paper, except for seven transparent sections, all organized in the same shape with six sections arranged in a rough circle, with the seventh section in the centre. On Each separate slide, the transparent sections are different shapes or designs, but within each slide the transparent sections are the same or similar. Each slide has a sticker in the corner to number it, and another to label it or provide use information.
