NGA Work - The Railway Painting: What Did You Find Out About It?

"Select a work of art that appeals to you (Pictures are attached) and write a one-page essay (double spaced, 12 point font size) Include the following:
(I have only 2 paintings for you, so choose one that you think you can write for essay the best)
1. Full title: artist (if known), title, date, medium.
2. Description of the work: What is it? What does it look like, etc. Describe what you see, not the information that is there.
3. Why did you choose it? Be specific.
4. What did you find out about it? How does it relate to the class material? Style, material, etc. Include a little information on the artist if there is one listed.
(You can include label information that's in the museum, but you do not need to do outside research. Make sure if you reference information that you say it was from the museum label or exhibition! It is plagiarism if you do not cite where you got it.) " >>> According to this, the label will be attached with pictures that I took pictures from National Gallery of ART Washington DC.
If you google, "Death of Saint Nicholas of Munster" you will see the paint and it's the same one that I attached with this order. With this paint, if you zoom in, you'll see lots of detail like little people around. I think it has a lot for you to write about.
(German Painting 1400-1530 >> Gallery 35A)
Another one is, The Railway, Edouard Manet. This one could be about freedom but I do not know if there's a symbol of the dog or not.
(Manet and Modern Paris >> Gallery 89)
So choose just 1 out of 2.
