Letter from Paul to Franz Lefmann, 25 April 1916

“France, 25 April 1916

Dear Papa,

Yesterday, the Hamburg Committee for War Libraries sent seven enormous parcels. I am practically digging through literature. Hamburg has once again shown itself from its noble side. This morning I was already looking for a new bookshelf.

Just these few lines for today, as you can imagine, I am up to my ears in work.

Warm greetings,

Your Paul.”
