Wall maps/wall-maps/wall maps (what dictates Webster?), from the sixteenth century on, were composed of multi-sheet woodcut, copper-engraved, or lithographed (or initially engraved and then transferred to litho stones) maps/charts printed down on to paper. Then, if requested - and paid for by the client(s) - colored by hand to/thru the 19th century; thereafter, with gradual perfection of chromo-lithographic printing - especially registration - techniques. Mounting on cloth would, again, be at clients' request and expense. Application of a varnish for 'protective' [!] purposes was a frequent extra, along with - notably in 19th and 20th centuries - attachment to a wooden roller at the top in order that the map might be suspended, unrolled, and re-rolled when not required: 'CRV' is frequently found in map catalogs and lists, meaning 'C[loth,] R[olled,] V[arnished]' (or variations in English thereof, usually explained in said map makers' & map sellers' catalogs). Alternatively, the insertion of metal-ringed 'eyelets' at top of the wall map, to facilitate suspension of map from hooks, is found. The varnish application, of course, became the 'bete-noir' (that's French . . .), as it discolored with atmospheric pollution and inherent breakdown of chemical constituents and age (but then we all do, don't we?). Doubtless others will supply more contemporary production techniques (such can be found, e.g., in general printing and publishing trade journals/periodicals)?

Can anyone point us to literature on how these wall maps were made? Of particular interest is how the paper map was printed and adhered to the cloth backing, what kind of cloth was used, and what is that varnish-like coating often seen on the surface of these maps, etc.. Thank you for your assistance!
