The seventh stop on the Great Crash of 1929: Tour of the Financial District is in front of 60 Broad Street, the former home of the now defunct Drexel Burnham Lambert. When this tour first started more than 20 years ago, Drexel Burnham Lambert was one of the most important firms on Wall Street, but several illegal trading convictions in the late 1980s led the firm to its collapse in 1990.
