The painter was a German national who had lived in the US, Emmanuel Leutze. The original was in a Bremen museum which was bombed. He also painted a full scale copy and a smaller one, which have never left the US.
The Dutch are also Germanic. Deutsch and Dutch are cognates, I believe they both simply mean “people” or “folk”.
My brother’s car is a 1990 Toyota Camry, and he got “classic vehicle” plates for it, simply because that means the property taxes are less.
Who bombed it, British or Americans?
The discussion of Washington Crossing the Delaware brought to mind that other “patriotic” painting, The Spirit of '76. This was painted by a guy from Ohio for the American Revolution Centennial exposition in 1876. After a tour of the United States, it ended up – for reasons that have never been clear to me – not in any museum, but in the Selectmen’s Room at Abbott Hall (City Hall) in Marblehead, Massachusetts. The building isn’t even open after hours or on weekends. If you want to see it, you have to come to the Hall during regular business hours during the week.
