Between the USA and Mexico there is a big wall. It is in the United States territory and it was built to avoid the illegal immigration from mexico to the United states on the fifth january 2021. it's about 727 km.
We have chosen this wall because it is very famous, long and big. It is very important for the USA history.

We think with Joan Miró's painting, this wall will be more cheerful because these paintings are extremelly colorfull.
