A 'lantern slide' is an early type of transparent photographic image, typically mounted between glass plates and projected using a magic lantern or similar device. It's an ancestor to modern slides and digital projectors. Think of it as a physical snapshot meant for sharing on a large scale. Lantern slides were a popular form of entertainment and education before the advent of film and digital photography. They're like a window to the past, offering glimpses into different eras. They required careful handling to prevent damage.
