Map of Manhattan gone ... ages before 9/11
Hey there, Hi there, Ho there,
the problem of how to deal with the map of Manhattan never occured in the wake of 9/11 as it had been replaced with a plain colored ground ages ago - not sure when exactly but well before 2000.
The logo of the Hotel New York does feature an excerpt of the skyline of NYC but is very, very, very stylized. Basically the only thing one could identify in it is the Empire State Building. The Twin Towers were not included so this didn't create a problem either.
Yours
Dirk
