Is it just me, or does the Obama/Biden logo have the "flavor" of the Pepsi logo? Not enough to make Pepsi mad, but just enough for you to think a little of Pepsi.
I should talk. I own my own real estate company now and our sign design/layout has a "flavor" of RE/MAX. Not enough to make RE/MAX mad (you REALLY don't want to do that!) but enough to give your brain a subtle background association with success. :-)
And, the fact that I was with RE/MAX for about 14 years may have influenced the design somewhat. ;-)
Anyway -- the Obama/Biden logo feels very refreshing to me! LOL! :-)
