Financial records of Pfefer's bookings and promotions range from full, itemized accountings of the expenses and income associated with a single event to one figure entries showing monies paid to a given wrestler for a specific booking. Generally speaking, Pfefer was an assiduous bookkeeper, and the records reflect this. Over the course of his career he maintained his business records in three basic ways. In the 30s and early 40s he generally made entries in account books, loose-leaf binders, or other volumes of sizable format. From the early 40s he recorded financial information in small notebooks, often keeping one year's figures for one wrestler in a given notebook. At about the same time he began keeping individual records or record groups in files of labelled envelopes. These three formats are separated out in the container list to this sub-series, as 1) account books; 2) files; and 3) notebooks. Individual records within each format are listed chronologically. The contents of the account books (which may be extensive) are described in some detail, while the files and notebooks are usually referenced to either 1) a venue/city or city (referring to the location of the matches to which the records pertain) or 2) a wrestler (referring to the individual to whom the records pertain).

The sub-series concludes with Pfefer's booking calendars, and records of tours booked.
