Cape of Good Hope Triangular Stamps
Partial Reading List Taken from ArticleOK, Al (
angore ), here is a list created from the references and suggested reading sources at the end of my article. It is not comprehensive, but it represents all of the sources that I could find related specifically to identifying Cape Triangles. I did receive some help from the APRL with a few of these, but 80-90% I found through my own research, mainly online.
