"For half of his 60 years, Zakheim has been in the mural-restoring business. His company, Nathan Zakheim Associates, provides a range of consulting and fine-art restoration work. At any given time he might be touching up a delicate 70-year-old fresco while at the same time recovering the vibrant details of some long-forgotten mural hidden under a spiky web of retaliatory gang tags along a stretch of transition road."
