I found these awesome poster ads for coca-cola in the Museum of Mayan Medicine.
Here are some close ups of the posters
Wreck Your Teeth! Drink Coca-Cola!
Always want Gastritis? Drink Coca-Cola!
These are brilliant on many levels. Since other people can say it better than I can I will quote from www.killercoke.org
“Coca-Cola is delicious. This is what many people who drink the beverage would say if they were not being exploited. Yet, this is not the case in Mexico; in Mexico, citizens, while also being exploited in terms of labor, are indirectly forced to drink Coca-Cola because of the lack of water supply due to Coca-Cola’s use of it. In order to perform such debasing acts, Coca-Cola is affiliated with political parties and advertises extensively throughout Mexico. Thus, in order to make a profit, Coca-Cola exploits the citizens of Mexico by depriving them of water and wages through its connection with the government and advertisements that will inevitably delay Mexico’s advancement in the future.”
