The above three logos have many similarities (color, shape, wavey lines). The logo at the left is the new Pepsi logo, the logo at the right is the old Pepsi logo, and the logo in the middle is a logo from President Obama's campaign.
I wonder if the creator of this Obama logo intentionally imitated the Pepsi logo so people would associate Obama with Pepsi?
The Pepsi brand was trademarked in 1903 and many people think of Pepsi as an American tradition. Obama certainly does not fit the traditional description of an American president...but maybe with a little help from logos and semiotics.
