9/11 Twin Towers postcard with an authentic Sept 11, 2001 postmark and original stamp.  There are over 30 different views of the Twin Towers available on this website.  These were purchased from a resident near Commack NY, who hurriedly stamped and postmarked all of these soon after the attack.    They have been stored in sturdy postcard holders and remain in very fine condition.    There is NO writing on any of the postcards.
