Thank you for the kind words HansHill! And for the tip. Postimages wasn't working yesterday but is today.

I mentioned her because I figured there was overlap between her cell or circle and Wiernick's cell or circle, likely through 'abraham'. I'd like to tie the whole atrocity propaganda industry together neatly if I can find a shoe that size, you know?
I think that's the case. I believe she probably wrote The Stroop Report but I don't want to get too far afield. It was a left wing group that was communist and Zionist and had connections to the Warsaw art scene. Look at Adolf Berman's brother: one of 3 people to run post-war Stalinist Poland.

Above. This is the picture in Donat's book, page 282 of "Engineer Galewski." Because Wiernik never mentioned his first name, that might be why no one else could either. Donat (who isn't honest in his own holocaust memoir but that's another story) writes "The photo we print was received from S. Willenberg (Israel). It's authenticity can't be verified so far." But Willenberg was supposedly in the camp and saw Galewski with his own eyes.

Above: Galewski the art director. He looks like the same person? But older and thinner?

Above, the art director Galewski.
I guess the assertion here is Krzywoszewski wrote "A Year in Treblinka" and added stuff from recent movies and names of his friends and that got blurred even with supposed Treblinka survivors? I don't know what it means but the "owner of a metal products factory" being the clown in A Year in Treblinka; and the owner of a metal products factory clowning around in Sportowiec Mimo Woli is too coincidental.
Another point is that from the story, Krzywoszewski and Wiernik were very close. Afterall Krzywoszewki helped him when he escaped. But at the Eichmann trial Wiernik mistakes him for another writer. It could be the translator screwed up, or it could be they never really knew each other, and Wiernik slipped up and mentioned another leftist art person:
Stefan Przybyszewski pseud. Józef, Władek (ur. 29 października 1903 w Krzywym Błocie koło Włocławka lub we Włocławku, zm. 21 kwietnia 1943 w Łodzi) – działacz komunistyczny.
Judge Halevi asks Wiernik: Did you join the underground?
Witness Wiernik: In Treblinka? Certainly. I was the liaison between the one camp and the other.
Q. I mean after the escape - which underground did you join after the escape?
(The judge is assuming that if you escape a deathcamp, that you'd then join up with partisans in the woods and fight for your people. But he's in for a surprise. )
The judge asks "which underground did you join after the escape)
Wiernik. After I escaped, I came to Warsaw. I had a Christian acquaintance, and I went to him - he was a writer named Stefan Przibishevski.
The attorney general steps in to try and answer for Wiernik: I am aware of these matters. This will undoubtedly help the witness. He has a certificate from the Polish Armia Ludowa, of which he was a member. And that will clarify the situation. If the Court is interested, he can hand it in.
Judge Halevi: I understood that you made your sketch during that period?
Attorney General: He has a certificate. It will immediately explain to which underground he belonged.
Witness Wiernik: I worked for the Warsaw municipality after my return.
Attorney General: The underground pseudonym of the witness appears there, as well as his real name, in order to certify that he was a member of the Polish People's Army, the Armia Ludowa.
Judge Halevi: [to witness] When you were a member of the Armia Ludowa, was it then that you drew this sketch?
Witness Wiernik: I prepared it when I was working in Warsaw in the Tashitza Palace. The SS was there on the one side, and I was a night watchman against air attacks - I also have a certificate about that. I used to sit there at night. Nobody disturbed me, and I gradually made that sketch.
Notice that escaping a death camp and casually writing a creative-writing account, is absurd, since one should have joined the underground and fought. And the attorney general tries to cover for this above. LOL.
