Willi Graf helps with “bulk mail” leaflets
I did not go to Scholl’s apartment till the next day around 6 pm. Hans and Sophie Scholl were busy sealing the leaflets that had already been addressed (Fellow Students) and getting them ready to mail.
I helped seal these so-called bulk mail [leaflets] and affixed postage stamps. Schmorell also participated in this work when he arrived later. I would estimate that there were between 800 and 1000 students who received the above-mentioned leaflet by mail. The addresses were taken from a student directory that I saw lying out at Scholl’s. This directory had a gray cover (this is correct, it was seized at Scholl’s).
