This report was gleaned from an article by writer/photographer Chuck Miller found at the link below.
It would be interesting to see the photos from World War I taken by this old camera.
Back plate of Kodak Vest Pocket Autographic camera. Note the autographic scribe tool just under the small door used for writing on the photo negative (“autographing").
The illustration shown above is form an old Kodak advertisement for their autographic cameras. The ad shows the autographic scribe tool in use and says, “You can now date and title your negatives, permanently, and almost instantly at the time you take them.”
...hat tip to Steve Collins for the link to this story.
