Ochsner Portrait
I did this portrait of Alton Ochsner Sr. around 1984.  It is in the clinic lobby next to the pay window. 
They used it in the TV ads for a few years.  One of the ads was an old man explaining to a kid who Alton Ochsner was.
As I remember, it is about 40x40 inches and is Oil on canvas.  There has been a physician in the Ochsner family since Paracelsus.  Pretty impressive.  New Orleans is very proud of this world famous hospital.
