The patent on these is just a few months shy of 100 years! There are 8 pictures, so go on to the next post after this one to see all the images.
I have no idea what they did. Obviously something to do with 8X10 and 7X11 film. Major whaddizit?
These will likely end up on Ebay I suppose. You'd sort of have to be an Eastman Kodak collector I guess.
$85 + $12 shipping in USA for both of them. More across the seas.
