The billboard...		The mural...
This billboard was made during the 1950's in the United States. Like other billboards of the time, it was produced during a time of market growth and U.S. capitalist competition. This context suggests that the main concern of the makers was to appeal to the 1950's clothing market.		Briefly, the mural was created following the Nicarguan Revolution. Murals at this time were often painted to make a statement by the people of Nicaragua who supported the Sandinista governement. This mural makes a strong statement about the aggressive relationship the U.S. had with Nicaragua during the 1980's.
