Take a look at the headers on these cereal boxes (General Mills' Kix in the background, Kellogg's Apple Jacks in the foreground.)
Notice how Kellogg's has mimicked the General Mills "G" logo with their loopy ampersand, and added a five-leafed plant logo oddly reminiscent of their competitor's "whole grain" symbol. Both headers also prominently declare "whole grain" goodness.
Coincidence? I think not.
