What's Inside That Wrapper?

Sometimes the wrapping is almost as curious as the item itself.  

In the case of vol. 4028a of the Mediceo del Principato collection at the Archivio di Stato in Florence, the 700 or so folios of handwritten newsletters stored here, mostly from Rome in the 1640s,  are divided into seven groups of roughly a hundred folios apiece, contained in seven individual folders or wrappings, blue in color and evidently recycled, having been turned inside out so that the former archival indications from a previous usage are on the inside back cover rather than on the front.  All are dated 1874, and all have a brief indication, partly printed or stenciled, and partly handwritten, of what they once contained.  For instance, on the back inside cover of the fourth fascicle, following a newsletter dated Rome, 31 December 1643, we find this inscription:  “1874: Affare 2970; categoria 6, Ogetto: lesioni casuali riportate da Vincenzo degli Innocenti.” Again, in the same place on the cover of the fifth fascicle, following a newsletter from Rome dated exactly one year later, we find, “Affare 2971; categoria 6, Ogetto: lesioni casuali riportate da Baldassini Carlo.”
