In July 1943, Wilhelm Wälder wrote the following message from Theresienstadt to Cornelius Vögele in Rexingen:
"My dear, so that you can see that I am often with you in thought, I send you and your family the best greetings today, me and my dear wife are well.
I am active here. The post office is doing very well here, parcels and postcards are arriving daily.
With warmest regards. Your old friend Willi Wälder.
Best regards to Kapfbeck."
Attempts were often made to send coded messages on postcards. The reference to the parcels and the greetings to the Kapf baker could be a request for food.
