Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.
This is a mysterious picture we found in my wife's family photos. The prone figure feeding the belt is marked with 2 small x's and is labeled "Franizcek", so he's probably the relative. The image is a photographic postcard (not lithographed) labeled on the reverse "Fronta Italie" and postmarked "K.u.K. Luftfahrtruppen Fliegerkompagnie Nr.22" I assume from the K.u.K. that this is the Austro- Hungarian army (or some other army where it was OK to point a rifle at your weapons instructor's head). But does Luftfahrtruppen and Fliegerkompagnie mean that this was an aviation unit? The machine gun mount looks odd, as if it is just a pipe on a stand, instead of a tripod. Is it an aircraft machine gun adapted for training purposes? Let's see those Shorpy experts go to work!
