Both Obey Clothing and Obama have utilized simple, sleek pop art designs in their campaigns. Both of these have a simplicity to them, but they are also unique and easily identifiable. These designs are also easy to interact with and change, getting people more exposed and involved to both parties.
Obama’s campaign literally turned him into a beacon of hope by making his image out of American flag colors and associates Obama with good preconceived notions. Obey, with it’s authoritarian, big brother feel, also draws in the viewer, but in the opposite way the Obama poster does. You don’t want to Obey the imposing figure on the poster, but you might want to be the figure being obeyed.
