The bulk of the collection consists of correspondence between Abraham and Amalie's children in England, Scotland and Austria, in particular letters to Marcel and his sister Regina (Regi). A major theme of the letters is the attempts to help the family members in Austria escape to Britain and the frustrations arising out of the difficulty of this.

There are also materials on German, Austrian and Czechoslovakian refugees’ life in Britain in the 1940s, as well as notes and texts written by George Vulkan on his family history.
