In the suburb or Humewood is a park called John Shelton Park with a stone pillar with marble plaque on it and everything. Problem is that the plaque only says "John Shelton Park" and doesn't say who John Shelton was. I'm curious but haven't found anything on the internet yet. The search continues.
Edited on 08/04/2013 - And Grant Slater comes to the rescue - "John Shelton, Director of Parks for Port Elizabeth, who had earlier helped with
the planning and construction of Maynardville, to design and build the Mannville
Open Air Theatre in St. George's Park." - Shakespeare in Southern Africa:
