This is a Kodak No. 2A Autographic Brownie camera, that once belonged to my grandfather.
The internet tells me that these cameras were made between 1916 and 1926. I like to imagine that in 2093 or so that my grown grandchildren will be taking photos of my iPhone with their futuristic cameras. By then cameras will probably be embedded in their eyeballs. Quote me on that! I predict the future!
