Hoosier Beer Geek Mike Atwood looks at Indiana's label art in the Indy Star. article
In other news, the new yellow dot on the Pepsi cans is not a nefarious plot. A friend tried to find out but the interweb didn't help so he wrote to Pepsico.
Thank you for taking the time to contact us at Pepsi-Cola.
To answer your question, that yellow dot is, in fact, a calibration marking for the can's coloring, and unfortunately, not a part of a promotion we're running. I apologize for any disappointment this may cause.
Again, many thanks for contacting us. We appreciate your interest in our company.
