As impressive as it is, all those details make it kind of ugly not as portable as other large systems. The map is HUGE in person. You have to unfold it at least 3-4 times before opening the rest up accordion style to see the full system. It's literally the size of a poster when fully open. When I visit I rip off everything except mid-town and lower Manhattan with part of Brooklyn. Even after that, it still has to be folded a few times to fit in my pocket. This is also due to the size they decided to print it
The London Underground map on the other hand is incredibly small for the size of the system but still very easy to read in person. As far as I know, NYC is the only map that is poster size when unfolded. All of the other large subway system maps that I've seen are generally 8.5"x11"ish or smaller.
Comparing the size of the NYC (422 stations) to London on the left (270) and Paris above (302) maps.
