35mm mounted slide
Transporting us back in time, these "slides" were a common presentation format a few decades ago. These 35 mm transparencies, carefully mounted on cards, required the aid of a "slide projector" to bring them to life during presentations. Within the archives, we house a remarkable collection of over 300 such slides, each encapsulating a unique visual narrative. This slide is from a presentation circa 1990s on the subject of arthrology.
