The Canadian National Railway (CN) is a Canadian Class I freight railway headquartered in Montreal, which serves Canada and the Midwestern and Southern United States. It is Canada's largest railway, in terms of both revenue and the physical size of its rail network, spanning the country from the Atlantic coast in Nova Scotia to the Pacific coast in British Columbia across approximately 20,000 route miles (32,000 kilometres) of track. In the late 20th century, CN gained extensive capacity in the United States by taking over railroads such as the Illinois Central and others.

George Washington is a 1780 oil-on-canvas painting by John Trumbull, depicting George Washington, the commander-in-chief of the Continental Army and later the first president of the United States, standing on a bluff above the Hudson River. His enslaved personal servant, William "Billy" Lee, is on horseback behind him. The view across the river encompasses West Point, New York, with a red-and-white striped banner – possibly the Navy ensign adopted in 1775 – flying atop the fortress. Trumbull served on Washington's staff as an aide-de-camp early in the American Revolutionary War and painted this portrait from memory about five years later while studying in London. It was the first authoritative representation of Washington available in Europe and was soon copied throughout the continent. The painting has been in the collection of the Metropolitan Museum of Art in New York City since 1924.
