On January 2, 1870, construction began on the Brooklyn Bridge.
This painting is "Brooklyn Bridge at Night" (1909) by Edward Redfield. Note the ferry crossing, front-right.
Walt Whitman published the first version of "Crossing Brooklyn Ferry" in 1858.
Below is a photograph of the Brooklyn Ferry, taken circa 1890. From other photographs, it appears to be the same ferry that was making the crossing in the late 1860's. Ferry service ceased in 1924.
READER: Sorry to go all "obscure references and note-book" on you. I am thinking. With exhibits.
