Overall, the skeleton is an important symbol in Mexican culture that represents a celebration of departed loved ones; yet, Hernández twists this positive Mexican image into an eerie symbol of poison. Being such a recognizable symbol, the skeletal woman bearing poisonous grapes represents the looming faith of the farm workers who worked in a polluted environment and of the people of Dinuba who drank contaminated water and ate contaminated food. Specifically, in the screen print, the dark shading of the grapes may illustrate the “lethal consequences of pesticides.” If Hernández were to draw naturally grown grapes, there may be less harsh shading and instead lighter shading to enhance a wholesome and nourishing appearance. Although many people associate Sun-Maid raisins with “the innocent pleasure of childhood,” this subversive alteration of the vibrant Sun-Maid depicts the “death-dealing lie” fed to the innocent people of Dinuba. In conclusion, Ester Hernández protested the use of pesticides through her screen print, "Sun Mad," believing it would reach hundreds of people in her community and spark a discussion about the tainted environment, food, and water they encountered.
