I've added a text box to each map, providing link to the original PDF build instructions. If you don't want to keep them on the board as reference, they're easily deleted.
And given the....ahem....gentle suggestions to make the top-down map images larger, I've gone back and tweaked all the boards posted so far. Every map pic now occupies as much space as possible within the GoogleDoc frame, with boxes and 3D ref image sidelined.
