This seems a little strange to me:

The government has told Rogue Ales to lower the flag on its American Amber
Ale. The Oregon brewery has been ordered to stop using the stars and stripes to
advertise American Amber. According to U.S. Code Title 4, Chapter 1, Section 8,
Item I: "The flag should never be used for advertising purposes in any manner
whatsoever." The company began brewing the beer 11 years ago, and uses the flag
on beer taps, pint glasses, posters and T-shirts. Even the company’s red, white
and blue delivery truck will have to be repainted. The order came after an agent
for the Alcohol and Tobacco Tax and Trade Bureau who was visiting Newport with
her family spotted a Rogue delivery truck with a flag painted on it.
