The most devastating stock market crash in the history of the United States;
Its from my favorite documentary by PBS - New York.

This particular part about Wall Street crash of 1929 is from episode 5 of the series with title: Cosmopolis
there are lots of archive photos, footages and drawings throughout the series and in my opinion it was great work done with finding them.

"Archival shoots took place at various historical and cultural institutions, including the New-York Historical Society, the Museum of the City of New York, and the Library of Congress, and focused on the filming of particularly rare or large-scale archival prints, lithographs, maps, and photographs" (less info)
