Below are some front pages of the Österreichisches Abendblatt (Austrian Evening Paper) from July 1933, when it published a series of articles on the supposed Jewish ancestry of Adolf Hitler.
I republished these not because I think there's any truth in them, but because they are part of the historical record, and the Press did become somewhat obsessed with claims of Hitler being Jewish in the summer of 1933.
The caption to the photograph reads: "Das Grabmal der Rosalia Müller, geborenen Hitler (die Familie hieß damals noch Hüttler). Das Grab steht aus dem judischen Friedhof zu Polna." [The gravestone of Rosalia Müller, born Hitler (the family was then still Hüttler). The grave is in the Jewish cemetery of Polna.]
The caption to the photographs reads "Die Gräber der Hitler auf dem Zentralfriedhof (israelitische Abteilung)" [The graves of the Hitlers at the [Vienna] Central Cemetery (Jewish Section)].
This page also quotes the director of the state museum in Polna as saying "Es gibt kaum einen Juden, der einem so schönen jüdischen Stammbaum hat, wie Adolf Hitler" (There is hardly a Jew who has such a beautiful Jewish pedigree as Adolf Hitler).
German historian Brigitte Hamann wrote in Hitler's Vienna [p.47] about this edition of the paper:"This time the newspaper published the pedigree of a Jewish Hiedler family in Polna, with a Klara Hitler, born in 1821, married name Pölzl, Braunau, Austria. [...] To be sure, this Jewish Klara would have been no less than seventy-eight years old at the time of Hitler's birth, and the other details would not have fit Hitler's grandmother. In part of the article in smaller print the newspaper backed off, stating that this Jewish Klara was neither Hitler's mother nor grandmother, but a close relative of the grandmother—which was false as well."
