Americans have a very unusual relationship with history, which manifests itself in, for example, people posing as beardless Lincolns or aging middle-class men performing “re-enactments” of what they think historical battles looked like. Greta Pratt has taken photos that show some aspects of this.
I don’t want to spend too much time writing about this, but just a quick comment. One of the things I noticed as a European living in the US is that most Americans I know keep telling me how Americans really don’t know anything about history. That’s simply not true. Americans do know about history. The interesting question is what they know - historical knowledge here is curiously selective.
