From left: The Knickerbocker Trust Company in 1904; in 1952, after its 1921 enlargement; and as it looks today.
From an article in the real estate section of the New York Times, March 5, 2009. Wikipedia also has an article on the building (there is a great period advertisement linked from there as well).
The article gives a history of the bulding, but it is hard to imagine from the building’s appearance today — not a trace of original facade remainds — what was there to begin with. Look inside the article also for a picture of original interior.
