Vtg New York City 9/19/2001 - 9/11 Service Distruption Ed MTA Subway Map For Sale

I was given these maps by a former NYC MTA worker who was an avid collector of MTA memorabilia. They are in really good condition. They were folded but not creased so that should be able to be flattened. The bottom right corner has some minor creasing.
100% authentic!!!!
This is a vintage official map issued by the MTA Metropolitan Transportation Authority for New York City. This is a very rare 11x17 printed paper map showing modified subway service post-9/11 as of Sep 19, 2001, released only a week after the horrific attacks. Incredible piece of NYC transit history..
