A more thorough explanation:

The Commission of Fine Arts is a group of people who work for the government. They help the President, Congress, and other government groups decide how to design public buildings, memorials, and parks in Washington D.C. They want these places to look good and fit in with the historic buildings and areas around them. The Commission of Fine Arts was started in 1910.

The Commission of Fine Arts might be asked to give advice on how to design a new memorial for a famous person. They would look at the area where the memorial will be built and make sure it fits in with the other buildings and parks nearby. They might suggest using certain materials or colors to make the memorial look good with the other things around it.
