You have gathered an amazing collection. The last picture is of course the same place as zmisiek correctly identified as the corner of Swietokrzyska and Nowy Swiat. The one you posted previously is curious, since it looks almost exactly like a photo in the book of T. Szarota "Okupowanej Warszawy dzien powszedni" (Everyday life in occupied Warsaw), with the board advertising glass panes (szyby
) and furniture (meble
) in the background. (Thus almost certainly 1939.) Only in Szarota's book there is a wagon carrying coffins in the foreground. In warsaw4.jpg one lamp post is removed, so I would say it is later than 1939 (everything that was metal was prone to removal by the Germans).
As for the bicycle shop, a sign in German is no proof that the shop was owned by a Volksdeutch, as it was speculated early in the thread. All Polish shops in Warsaw were supposed to have signs in German since late 1939 (Polish was allowed, but only together with German). It was not required for Jewish shops, so if you see Polish-only signs, good chance it's a ghetto photo. Speaking of which, a Jew with an armband may as well appear in a photo of pre-getto Warsaw or even post-ghetto 'aryan' part (some Jews were allowed movement outside getto). Jews in Warsaw were forced to wear armbands as early as 1 December 1939 (after Tomasz Szarota "Okupowanej Warszawy dzien powszedni"). So classification of a place is not always obvious.
warsaw19402007f.jpg looks suburbian, lots of space, low buildings. Nothing like the part surrounding ghetto (more like Praga, on the eastern side of Vistula). I think the wooden fence is just an ordinary fence.
