File includes the original paper folder for the invoices, which has been annotated to read: "Sample 3 months [April-June] of invoices showing the costs of running the JM Warehouse at 65 Clerkenwell Road." Hallam Murray (b 1950) is noted on this same folder as having run the warehouse between January 1981-December 1987. A small number of invoices are also present for March 1982. A manuscript contents listing for the file is present for April-June also.
