Making the map of all the flags of the municipalities of Spain, day 2 Madrid

For now there is good progress, I know it will take time, but by both my balls this is over!

By the way, the municipalities that appear with a "?"are the ones where I did not find that they have a flag, neither on their official pages nor on Wikipedia, so I will assume that they do not have one, if I am wrong about this I appreciate corrections 👍.
