If the German military photographed Trawniki conscripts for their ID cards, then the photographer might be expected to hand his photographs not to the recruits themselves whom the Germans might expect to damage or lose them, or perhaps even swap them for purposes of nefarious misidentification, but rather might be expected to hand them to the staff responsible for creating ID cards.  Prior to attachment to a card, then, its photo might be expected to have little opportunity for abrasion or wear.

And after attachment, the photo would lie folded inside its ID Card, during which time the enveloping card would afford it protection from abrasion and wear.

Of the four Trawniki ID Cards which the Kremlin has released in high-resolution-with-color Munich versions, three come with photographs attached, the corners of which are shown below, and where the small wear expected on a typical Trawniki-Card photo might resemble that of Juchnowskij 847, and in comparison to which Demjanjuk 1393 appears dog-eared.  Wolembachow 1211 lies somewhere in between, possibly closer to Juchnowskij than to Demjanjuk, particularly when it is recognized that its lower-left corner shows not normal wear but damage resulting from the Kremlin punching a hole so that the card could be skewered on a binder ring, and which exposed the photo in the vicinity of the ring to stress and to accelerated wear.

As the Kremlin has released 44 of the 48 cards only in pdf format, comparison of the degree of wear of their photos is not feasible because of the low quality of their images.  If the Kremlin were to provide high-definition-with-color Munich-quality reproductions for all cards, then among the first questions that might be profitably investigated is where Demjanjuk-card wear ranks compared to the wear of all other cards.
