While listening to Washingtons Crossing by David Hackett Fischer, I learned some interesting things about this famous painting including:
The painting is huge, 20 feet wide and 12 feet high.
Painted in 1851 by a German-born Emanuel Leutze.
The first copy was damaged by a fire, restored then destroyed by a bombing raid by the British during WWII.
A second copy was completed in 1851 and sent to the US, and is now at the Metropolitan Museum of Art in NYC.
Read the introduction to the above book about the painting here:
