Who is this guy in the painting?! How did he merit a painting? What's unique about the style/composition/whatever?
Conversely, I went to an exhibit of Napoleonic Art and they had a whole breakdown of the symbolism. For example, Napolean liked bees as a symbol of hard work and order, apparently, and they were snuck into most depictions of him as little Easter Eggs.
Most paintings dont have a cool backstories. They are just paintings. Art student can see technical details of how they were done, but those are not really interesting if you are not trying to learn to paint.
We pointed this out to a worker that day. Several years later, we went back to see that the exhibit had not changed. I'm not sure if it's still there today.
