This document is in black and white, and this is a cartoon. This document represents the frontier between United States and Mexico, build by the americans to prevent mexican immigration ,the man with his hat and his bag who wanted to go to USA. We can see the size difference between this man and the Statue of Liberty which shows the american power. The author denunce the fact that americain reject immigration in their country. The message has been heard but a wall still remain between those countries. We know that a part of south america belonged to the Mexico before , such as Texas for example.
I hope that will help you ! Good luck girldrectioners! ;)
