"Kingston Ontario Experimental Photo Map" print by the Department of National Defence (1968)

In the late 1960s Canada's Department of National Defence experimented with using high-altitude colour aerial photomosaics to form a map’s base layer, then graphically  highlighting and labelling roads, trails and tracks after the fact. Here we have a 1968 example of such a map from the York University map library showing Kingston, Ontario, and environs from Eel Bay to the St. Lawrence River. 

A reproduction available at 12x16" or 18x24" on Epson Enhanced Matte 192 gsm paper printed with Epson UltraChrome XD2 archival ink. Sold in an open edition, unframed. Based on this original public domain image held by the York University Digital Library.
