Jack in the Box® restaurants has kicked off an exciting promotion for Warrior fans.

Jack in the Box® restaurants are now offering a retro antenna ball, featuring a white football helmet and the "menehune/rainbow" logo. Dubbed "Throwback Jack," the limited-edition antenna ball is available free, while supplies last, with the purchase of any large combo meal at Jack in the Box restaurants in Hawaii now.

"Whether you're an incoming freshman, seasoned alumni or just a fan of the university, this is a great opportunity to show your UH pride while helping the Warriors kick off their 2010 football season," said Donna Yano, vice president for Jack in the Box Hawaii. "Although the university retired the old logo in 1982 after nine seasons, it still resonates among longtime UH supporters. Each 'Throwback Jack' comes with a flexible post and suction cup, so even if you don't have a car antenna, you can still show your UH pride by affixing it to any glass surface."

(NASDAQ: JACK), based in San Diego, is a restaurant company that operates and franchises Jack in the Box® restaurants, one of the nation's largest hamburger chains, with more than 2,200 restaurants in 18 states, including 25 locations in Hawaii.
