A teenager who painted a "Vote Obama" mural on his grandparents' fence in Denver says appeals ensure the work will remain at least through the election.

Denver officials say the mural, which features a portrait of Sen. Barack Obama, the Democratic presidential nominee, and a call to vote for him violates city ordinances on the size of political signs, The Denver Post reports. The mural is well over the 8-foot-square limit.

Paul Trujillo and two friends used spray paint to create the mural after Obama, D-Ill., was nominated in Denver in August.

"I want to use my fence to communicate to the rest of the world," Trujillo said.

Esther Vigil, Trujillo's grandmother, said she has received offers to pay the $150 fine for failing to remove or cover up the mural. But Trujillo said he has learned that an appeal of the removal order comes with a 45-day extension, enough to get it past Election Day.
