In the era of independent nautical charts before the establishment of the Coast Survey, the Depot de la Marine, and the Admiralty, it was not uncommon to list sources on maps to emphasize that he charts were made from actual observation.

Had this marketing technique been used before by map makers?

I would suggest a few amendments to the Woodcut section so as to make clear that the process is the reverse of that for copper engraving,i.e. what is printed is what is left standing rather than cut away. Significantly, in the context of modern copies, there is usually no visible platemark (since printing a woodblock did not require the same degree of compression that produced the copperplate print). This makes it much more difficult to detect modern versions of woodcut maps. Can I perhaps highlight the section on the 'Map History' site devoted to 'Cartographic Fakes, Forgeries and Facsimiles likely to deceive' . This includes an index of all those so far identified, with notes on the more significant ones. Additional information would be welcomed. Thank you for the number of good comments you make above.
