So, what is real and what is a fake?
There is the rub! Real is what is real and fake is what is fake. Again, clear as mud.
Let's look at the production of a "real" map. A real map is engraved by the mapmaker on wood, copper plate or steel. It's an engraver's art.
The map is then printed from that medium to paper, then colored or not, and published in an atlas or as free maps.
The printing of the original map may go on for years. Therefore, an "original" map may be the first printing or subsequent printings. It all depends!
Yes, it's that confusing.
