A woman walks past a graffiti depicting Venezuelan President Hugo Chavez in Caracas Janaury 7, 2013. Chavez's formal swearing-in for a new six-year term scheduled for Jan 10 can be postponed if he is unable to attend due to his battle to recover from cancer surgery, Venezuela's vice-president Nicolas Maduro said.
