PHOENIX -- Arizona's centennial celebration is under way at the Capitol in Phoenix as residents celebrate the state's 100th birthday.
Gov. Jan Brewer shouted "happy birthday Arizona" from a stage in front of the domed Old Capitol at the start of festivities.
Those included story-telling, musical acts, displays and dancing.
Additional events included a ceremony to issue an Arizona statehood postage stamp and a performance by violinist Itzhak Perlman in the Arizona Senate chambers.
On Feb. 14, 1912, Arizona became the last of the states formed in the contiguous 48 states.
