I just received this map backed with the Synapses map on the other side.
I was a little surprised to see it was just a rolled up poster, and not an actual board, but that's not a huge issue. The bigger problem was that the image quality is really poor. It appears that they found a human body image online at about 500x700px, and just blew it up to poster size before overlaying a hex grid. The Synapses side is just as pixelated.
Is this actually how all copies of this map look?
Yes. I still think the Human Body side looks great even if it is a bit pixelated. The Synapses side graphics make a difficult to understand map even more difficult to understand. The squiggles and blobs are kind of fuzzy and the "City" colors are just the slightest hint of a color making it difficult to see what colors go where.
