The New York Transit set includes subway maps for Manhattan (showing all of Manhattan and part of the Bronx) and for Brooklyn/Queens, which together give almost the entire system.

Each map is printed on a plastic stock which is paper-thin but incredibly durable (similar to a MetroCard). These maps do not fold out; the maps are printed on the front and back of the cards.
