Original glass magic lantern slide images showing an early "Flying Boat" - Guessing these are from the 1910s-20s era but acquired as-is

A magic lantern slide viewer is a device used to view glass slides with images, typically from the 19th or early 20th century. It works by shining light through the transparent slide and projecting the image onto a wall or screen, or sometimes allowing direct viewing through a magnifying lens. These viewers were part of early image projection technology and are considered precursors to modern slide projectors.

Very unique piece showing a plane with theater advertising on the side

Crazy early press photograph showing the scale of a Hannibal aircraft landing wheel with a Ford Model A (or similar) automobile

Incredible framed photos showing the one off Gazda Helicospeeder prototype. One of the photos appears to be signed by "Tony Gazda" who I believe is the designer Antoine Gazda (not authenticated, as-found). That photo is dated 1945.

Very rare and unique pieces
