This is a Eastman-Kodak autographic folding Brownie, model 2-A (or 2A; I've seen it typed both ways.) I bought it for decoration, so I'm not sure if it works or not. I saw an old print ad for this type of camera on a YouTube video on horror video games, and well....

An autographic camera is the kind where you had special film where you could write descriptions on it and those descriptions would appear on the picture itself when it was developed.
This camera started selling in 1915 and stopped being sold in 1926, but I think this camera was likely made between 1919 and 1923. It has the round case that came about in 1917, and the ball-bearing lens, which was made until 1923. I think the foot at the front is the newer c-shape and not the s-shape of earlier models, which means it likely was made after 1918.
Just in case you are curious, I pulled various bits from these two sites (and two videos)

https://www.youtube.com/watch?v=kzojmBk9sfM (This guy provides more information about the technical aspects of the camera, including a better explanation of what an autographic camera is.)
Of note, my camera has different numbers for the apertures than the two cameras in the video, more in line with the camera in the second link. So it may be on the slightly earlier side; I'm not sure.
