In 2006, the sculpture of Morton McMichael, located at Sedgely Drive and Lemon Hill Drive in East Fairmount Park, received conservation treatment.  Treatment included removal of the extensive corrosion and staining by walnut shell blasting, in addition to the application of a patina to even out the surface.  The sculpture was then coated with a microcrystalline wax to protect it from the elements.
