Handwritten inscription on the back: “To the Wassers that they may remember what I look like. ” Szlamek, Warsaw, March 18, 1942”.

Szlamek (probably Shloyme Fajner), imprisoned on January 5, 1942, in the cellar of the Chelmno Castle, was appointed to a team of gravediggers. He succeeded in escaping on January 19, and reached the city of Piotrkow where the registration office of the local Judenrat provided him with forged ID in the name of Jakub Grojnowski. Then he was taken in and hidden in Warsaw by Hersz Wasser, Secretary of Oyneg Shabbes. Bluma Wasser wrote the transcription of Szlamek’s detailed account of how vans were used as mobile gas chambers to assassinate Jews and Gypsies.
