Ian Ference's 3D blog on all things stereographic, from classic scopes & stereoviews to historical context & modern analysis
One of the items in Andrew O. Fasser's collection of stereo slides is a box, which originally held Verascope Richard 6x13 diapositives, simply marked "Belgium". Inside are 16 slides of Great War devastation; the best 8 are examined.
The Tranchée des Baïonnettes - where 21 men of the 137th Infantry's 3 Company were supposedly buried alive, with only their bayonets poking out above the earth - was photographed after it was excavated during the planning phases of the 1920 monument built on the site.
