Eric Darton’s Divided We Stand: A Biography of New York’s World Trade Center was published in January of 2001, just eight months before 9/11 would deeply brand the image of the twin towers with exactly the opposite sentiment. To right, a sparkly Dufex foil print I bought in early 2002 that recalls the mood. The reverse is marked “Dufex Prints / Printed in England / Pictures Colour Library / Reference Number 409359.”
Darton’s book is fairly well-reviewed on Amazon. There’s a new self-aware edition as of August 2011.
