Receipts and other materials formerly housed in small brown expanding file have been removed to folders to aid in preservation, but they have been kept in the same order and organization, with items from each section of the file stored together in acid-free envelopes. The expanding file itself is stored in Box 40. Images of the expanding file before receipts were removed are also included in Box 15/Folder 1. Receipts include both business and general household receipts.
