From July to August 1999, there was an exhibition titled “Do you know Jelabuga ?” in the Culture Museum of Osnabruck/ Felix-Nussbaum. This was the first time the secret pictures taken by Klaus Sasse in Soviet POW camps in Jelabuga, Selenodoksk and Kolstau in 1945-1947 were displayed in large quantities. Klaus Sasse used his 1938 Minox Riga camera to secretly record the images in these POW camps on four rolls of 50 exposure VEF Minox films. There were a total of ninety pictures with extensive text at display. After the war, Klaus Sasse used pseudonym Konigberger published a few of his Minox pictures about POW camps in Germany, but most of his images were not published. This was the first time he went public.
A Minox Riga camera played crucial roles in capturing these POW camp images, at great personal risk. any other camera was not possible. (text courtesy to http://www.greenspun.com/bboard/q-and-a-fetch-msg.tcl?msg_id=002Kjg)
