The Original 9/11, Except it was on 9/16
This was a bit of history I never knew:
"Wall Street bomb." Aftermath of the explosion that killed dozens of people in New York's financial district on September 16, 1920, when a horse wagon loaded with dynamite and iron sash weights blew up in front of the J.P. Morgan bank at 23 Wall Street. The attack, which was attributed to Italian anarchists, was never solved. 5x7 glass negative, George Grantham Bain Collection.
