I added a slideshow to my website of some of my cameras, sometimes with the instruction booklet or an original photo made with such a camera. Below an example of an extremely rare military Kodak from 1916, together with a rare print of WW1 soldiers, one with a camera.
Over the next weeks I will add new photos.
There is a Eastman Interchangeable View camera from around 1887 for sale on eBay. Only 2 days to go. See for yerself here.
