A collection of pocket notebooks kept by Olof, in which he jotted down information such as addresses, expenses, costs for buildings he worked on, to-do lists, birthdays, and more. Each notebook has a “table of contents” written by Olof in the front, indicating what types of information he used that particular book for. Also includes a leather card case with calling cards for Agatha (as “Mrs. Olof Hanson”) and Olof.
