Interesting question. I believe they're just random although both photos come from the same huge collection of photos. Only about twenty percent of the photos are marked with date and place and the balance, like these two, are unmarked.
I did find find an Internet reference to this name as follows:
Dr. Wilhelm Gottlieb Papke Dienstgrad: Oberarzt Born:1902 Died: 16.Aug.1941 Place of death: Arm.Sanko 1/562 mot. F.Laz. Uman; Dr. Wilhelm Gottlieb Papke has probably been re-interred in a Sammelfriedhof (collective cemetery) in Kiev, Ukraine as an unknown soldier according to this source:Graebersuche(Grave search)Online at Volksbund Deutsche Kriegsgräberfürsorge e.V. - Arbeit für den Frieden
Danke.
I don’t know what the topic of the thread is but by coincidence I was looking papke up on the net and came across this. i was drawn to his identity by a photo of his grave with a helmet mounted on top in a Youtube video series “unpublished German Photos of the war in Russia 1941-45. I think it was Episode 2 or 3. I was not expecting anyone else to be looking for him.
