Used Photoshop, not some BS online Obama poster generator.
I think there's 2 ways you could look at this:
"LOL SHE MADE A FUNNY WORD CHENGE LOLOLOL"
or that it's almost kinda comparing 2 highly recognizable political icons who both aimed to change things. No matter what you think of Che Guevara and Barack Obama, you have to admit that both of them are really iconic and were into change.
I'm planning on making this into a huge poster thing and putting it up as street art. I know just where too.
