The mural is in the heart of the traditional Boca neighborhood that is home to the imposing Bombonera stadium where Maradona once played for domestic giants Boca Juniors.
Maradona, who died aged 60 following a heart attack at home on Wednesday, will lie in state at the pink-hued Casa Rosada presidential palace from Thursday through Saturday. Huge crowds are expected to visit his casket as part of three days of national mourning declared by President Alberto Fernandez.
